Neuron terdiri dari tiga bagian utama, yaitu..
- A.
A. akson, dendrit, dan badan sel
- B.
B. akson, sel schwann dan dendrit
- C.
C. dendrit, badan sel dan badan Nissl
- D.
D. akson, badan sel dan badan Nissl
- E.
E. akson, selubung mielin dan badan sel
Correct Answer
A. A. akson, dendrit, dan badan selExplanation
The correct answer is A because it accurately identifies the three main parts of a neuron. The axon is responsible for transmitting electrical signals, the dendrites receive signals from other neurons, and the cell body contains the nucleus and other essential organelles.Rate this question:

Antara neuron satu dengan neuron yang lain dihubungkan oleh.....
- A.
A. neurit
- B.
B. dendrit
- C.
C. sinapsis
- D.
D. sel Schwann
- E.
E. selubung mielin
Correct Answer
C. C. sinapsisExplanation
The correct answer is C. sinapsis. Sinapsis adalah koneksi antara dua neuron yang memungkinkan transmisi sinyal listrik dari satu neuron ke neuron lainnya. Sinapsis terbentuk melalui kontak antara ujung akson dari satu neuron dengan dendrit atau badan sel neuron lainnya. Dalam sinapsis, sinyal listrik yang dihasilkan oleh neuron pengirim akan diubah menjadi sinyal kimia dan kemudian disampaikan ke neuron penerima.Rate this question:

Susunan syaraf pusat pada manusia, adalah....
- A.
A. sistem syaraf tepi
- B.
B. sistem syaraf simpatik
- C.
C. sistem syaraf parasimpatik
- D.
D. sistem syaraf otonom dan otak
- E.
E. otak dan sumsum tulang belakang
Correct Answer
E. E. otak dan sumsum tulang belakangExplanation
The correct answer is E. otak dan sumsum tulang belakang. This is because the central nervous system in humans consists of the brain and spinal cord. The brain is responsible for processing and coordinating information, while the spinal cord serves as a pathway for transmitting signals between the brain and the rest of the body. Together, they form the central nervous system, which controls and regulates various bodily functions.Rate this question:

Bagian otak besar yang berfungsi sebagai pusat pendengaran yaitu...
- A.
A. pons varolli
- B.
B. lobus parietallis
- C.
C. lobus frontalis
- D.
D. lobus oksipetalis
- E.
E. lobus temporalis
Correct Answer
E. E. lobus temporalisExplanation
The correct answer is E. lobus temporalis. The lobus temporalis is the part of the brain responsible for processing auditory information and is therefore considered the center for hearing. The other options mentioned in the question are not specifically related to the function of hearing.Rate this question:

Hipotalamus merupakan bagian otak yang berfungsi....
- A.
A. mengatur perasaan
- B.
B. mengatur suhu tubuh
- C.
C. mengkoordinasi gerakan otot
- D.
D. mengatur keseimbangan tubuh
- E.
E. menghubungkan otak besar dan sumsum tulang belakang
Correct Answer
B. B. mengatur suhu tubuhExplanation
The correct answer is B. mengatur suhu tubuh. The hypothalamus is a part of the brain that plays a crucial role in regulating body temperature. It acts as a thermostat, monitoring the temperature of the body and initiating responses to maintain homeostasis. It can trigger mechanisms to increase or decrease body temperature, such as shivering or sweating, in order to keep the body within a narrow range of optimal temperature.Rate this question:

Seseorang terjatuh dan kepalanya terbentur batu. Dia berdiri berjalan sempoyongan dan akhirnya terjatuh. Kemungkinan besar bagian otak yang mengalami gangguan yaitu...
- A.
A. serebrum
- B.
B.diensefalon
- C.
C. otak tengah
- D.
D. serebellum
- E.
E. sumsum tulang belakang
Correct Answer
D. D. serebellumExplanation
When someone falls and hits their head on a rock, causing them to stumble and eventually fall, it is likely that the part of the brain that is affected is the cerebellum. The cerebellum is responsible for coordinating movement and balance, so any disruption to this area can result in difficulties with walking and maintaining equilibrium. Therefore, it is the most probable answer in this scenario.Rate this question:

Fungsi neuron sensorik pada lengkung reflek lutut adalah....
- A.
A. menyampaikan impuls ke effektor
- B.
B. menyampaikan impuls ke reseptor
- C.
C. menyampaikan impuls ke otak depan
- D.
D. sebagai syaraf penghubung ke dalam saraf pusat
- E.
E. menyampaikan impuls ke sum-sum tulang belakang
Correct Answer
E. E. menyampaikan impuls ke sum-sum tulang belakangExplanation
The correct answer is E. menyampaikan impuls ke sum-sum tulang belakang. Neuron sensorik pada lengkung reflek lutut berfungsi untuk menyampaikan impuls atau sinyal dari reseptor (sensor) di lutut ke sum-sum tulang belakang. Impuls ini kemudian akan diproses di sum-sum tulang belakang sebelum dikirim ke otak untuk diterjemahkan sebagai sensasi atau gerakan yang dibutuhkan.Rate this question:

Serabut saraf otak yang berfungsi sebagai neuron sensorik, yaitu...
- A.
A. I, II dan VIII
- B.
B. I, III, dan IV
- C.
C. II, IV dan VI
- D.
D. II, VI dan VIII
- E.
E. III, V dan VII
Correct Answer
A. A. I, II dan VIIIExplanation
The correct answer is A. I, II, and VIII. This is because the question is asking for the nerve fibers in the brain that function as sensory neurons. Sensory neurons are responsible for transmitting sensory information from the sensory organs to the central nervous system. In this case, option A includes the nerve fibers I, II, and VIII, which are the olfactory nerve, optic nerve, and vestibulocochlear nerve respectively. These nerves are involved in the senses of smell, vision, and hearing, making them sensory neurons.Rate this question:

- B.
B. 2
- C.
C. 3
- D.
D. 4
- E.
E. 5
Correct Answer
D. D. 4Explanation
The question is asking for the part of the nerve cell that transmits impulses from the cell body to other nerve cells. Option D, which is 4, is the correct answer as it represents the axon, which is responsible for transmitting electrical signals away from the cell body to other neurons or muscles.Rate this question:
