Latihan Soal IPA Kelas 4 Tentang Panca Indra

The correct answer is "hidung" because the sense of smell is primarily perceived through the nose. The nose contains olfactory receptors that detect different scents and send signals to the brain for interpretation. The other options, such as the ear, skin, and tongue, are not primarily responsible for detecting smells.

If someone is experiencing ear pain, they should go to a specialist called an ear, nose, and throat (THT) doctor. This doctor specializes in diagnosing and treating conditions related to the ears, nose, and throat. Since the question mentions ear pain, it is important to seek the expertise of a THT doctor who can provide the appropriate medical care and treatment for the specific issue.

The correct answer is "papila". "Papila" is the Indonesian term for taste buds, which are small bumps on the surface of the tongue that contain the sensory receptors for taste. The other options - pupil, vanila, and gorila - are unrelated to taste buds and do not provide an accurate explanation for the given question.

When there is bright light, the pupil of the eye will constrict or become smaller. This is a natural response to protect the retina from excessive light exposure. By narrowing the pupil, less light enters the eye, reducing the amount of light that reaches the sensitive cells in the retina. This helps to prevent damage to the retina and maintain optimal vision in bright conditions.

The given options describe the functions of the tongue, and the question asks for the function that is not included. The options include "as a sense of smell," "as a speech organ," "as a sense of taste," and "to regulate the position of food and assist in swallowing." The correct answer is "as a sense of smell" because the tongue is not directly responsible for the sense of smell, but rather the olfactory receptors in the nose perform this function.

The correct answer is A because eating foods that are rich in vitamins can help maintain eye health. Vitamins, such as vitamin A, C, and E, are essential for the proper functioning of the eyes and can help prevent eye conditions like macular degeneration and cataracts. By consuming a diet that includes fruits, vegetables, and other nutrient-rich foods, we can provide our eyes with the necessary vitamins to support their health and function.

The correct answer is "alis mata" because the eyebrows (alis mata) function to protect the eyes from sweat flowing from the forehead. They help to prevent sweat from entering the eyes and causing irritation or discomfort.

Panu adalah salah satu jenis penyakit kulit yang disebabkan oleh infeksi jamur pada kulit. Infeksi jamur ini biasanya terjadi pada area tubuh yang lembab dan hangat, seperti lipatan kulit, selangkangan, atau daerah di sekitar alat kelamin. Gejala panu umumnya berupa bercak merah atau coklat yang terasa gatal dan bersisik. Penyakit ini dapat diobati dengan menggunakan krim atau salep antijamur. Katarak, anosmia, dan anemia bukan termasuk penyakit kulit, melainkan masalah pada mata, gangguan penciuman, dan kekurangan zat besi dalam darah.

The correct answer is "selaput bening" because the question states that the cornea of the eye is clear and does not contain blood vessels. Therefore, it can be referred to as "selaput bening," which means a clear membrane.

Rambut halus dan selaput lendir berfungsi untuk menyaring udara. Rambut halus di dalam hidung bertugas menangkap partikel-partikel kecil seperti debu, serbuk sari, dan bakteri yang masuk ke dalam hidung saat kita bernapas. Selaput lendir juga berperan dalam menyaring udara dengan menangkap partikel-partikel tersebut dan mencegahnya masuk lebih jauh ke dalam saluran pernapasan. Dengan demikian, fungsi utama rambut halus dan selaput lendir adalah untuk menjaga agar udara yang masuk ke dalam tubuh kita lebih bersih dan bebas dari kotoran.

The given statement "Ujung lidah peka terhadap rasa manis" translates to "The tip of the tongue is sensitive to the taste of sweetness." This suggests that the taste buds located at the front part of the tongue are more responsive to detecting sweet flavors. This explanation aligns with the concept of taste perception, where different regions of the tongue are more sensitive to specific tastes.

The correct answer is "indera peraba" because individuals who are visually impaired rely on their sense of touch to read Braille. Braille is a system of raised dots that can be felt with the fingertips, allowing blind individuals to interpret and understand written information through touch. This sense of touch is their primary means of accessing written material, making the sense of touch or "indera peraba" essential for reading Braille.

The iris and pupil are responsible for regulating the amount of light that enters the eye. The iris is a circular muscle that controls the size of the pupil, which is the black hole in the center of the eye. When there is too much light, the iris contracts, making the pupil smaller to reduce the amount of light entering the eye. Conversely, when there is low light, the iris expands, making the pupil larger to allow more light in. Therefore, the iris and pupil work together to adjust the amount of light entering the eye according to its needs.

The correct answer is katarak. Katarak is a condition where the lens of the eye becomes cloudy, leading to blurry vision. In this condition, the lens needs to be removed and replaced with an artificial lens through a surgical procedure called lens extraction. This procedure helps improve the vision of individuals with cataracts.

Vitamin E is essential for maintaining healthy skin. It is an antioxidant that helps protect the skin from damage caused by free radicals, which can lead to premature aging and skin problems. Vitamin E also helps in moisturizing the skin, reducing inflammation, and promoting healing. Including foods rich in vitamin E in our diet can contribute to overall skin health and appearance.

Miopi adalah kondisi ketika mata tidak mampu melihat benda-benda yang letaknya jauh dengan jelas. Pada miopi, fokus cahaya yang masuk ke mata terjadi sebelum mencapai retina, sehingga gambar yang terbentuk di retina menjadi kabur. Hal ini biasanya disebabkan oleh bentuk mata yang terlalu panjang atau lensa mata yang terlalu cembung. Untuk mengatasi miopi, biasanya menggunakan kacamata atau lensa kontak dengan lensa negatif untuk membantu memfokuskan cahaya ke retina.

Anosmia is the correct answer because it refers to the inability to perceive smells. Anemia and leukemia are unrelated medical conditions involving blood disorders, while defisiensi is not a recognized term in this context. Therefore, anosmia is the most appropriate choice as it directly relates to the inability of the sense of smell.

The correct answer is "kulit ari". Kulit ari refers to the outermost layer of the skin that is composed of dead cells that continuously shed and are replaced by the cells underneath. This layer acts as a protective barrier for the underlying layers of the skin.

The ability of the eye lens to change its curvature in order to focus on objects at different distances is called "daya akomodasi" or accommodation power. This adjustment allows the eye to maintain clear vision both up close and far away.

The correct answer is retina. The retina is the layer of tissue located at the back of the eye that contains cells called photoreceptors. These photoreceptors, known as rods and cones, are responsible for detecting light and converting it into electrical signals that can be interpreted by the brain. The other options mentioned, such as the cornea, pupil, and iris, are all parts of the eye but do not directly receive light stimuli.

The given statement mentions that the color of the eyes varies from one nationality to another, hence it is also referred to as the rainbow membrane. The term "iris" refers to the colored part of the eye that surrounds the pupil and controls the amount of light entering the eye. Therefore, iris is the correct answer as it directly relates to the description provided in the statement.

The correct answer is "lensa". The lens of the eye is responsible for focusing and directing incoming light onto the retina. It adjusts its shape to allow for clear vision at different distances. The iris controls the size of the pupil to regulate the amount of light entering the eye. The cornea is the transparent outer layer of the eye that helps to focus light. The retina is the light-sensitive layer at the back of the eye where images are formed.

The correct answer is "daun telinga" because the earlobe, or "daun telinga," acts as a funnel and collector of sound vibrations. It helps to direct sound waves into the ear canal and towards the eardrum, allowing us to hear. The other options, such as the Eustachian tube, cochlea, and tympanic membrane, have different functions in the ear but are not specifically responsible for funneling and collecting sound vibrations.

The correct answer is diafragma. The question is asking for something that functions similarly to the pupil of the eye in a camera. The pupil controls the amount of light that enters the eye, and the diafragma in a camera also controls the amount of light that enters the camera by adjusting the size of the aperture. Therefore, the diafragma is the correct answer as it performs a similar function to the pupil in regulating the amount of light.

The correct answer is "lapisan dalam." This is because the saraf penerima rangsang (sensory nerves) are located in the inner layer of the skin, which is known as the dermis. The dermis is responsible for receiving and transmitting sensory information such as touch, pressure, temperature, and pain. The epidermis is the outermost layer of the skin and does not contain sensory nerves. The term "kulit ari" is not a correct anatomical term and does not refer to a specific layer of the skin.
