Rangka memiliki fungsi sebagai berikut, kecuali . . . .
Correct Answer
C. Membentuk sel-sel otot
Explanation
The correct answer is "Membentuk sel-sel otot". The skeletal system does not form muscle cells. Instead, it provides support and structure to the body, allows for movement, protects internal organs, and produces blood cells. Muscle cells are formed through a different process called myogenesis, which involves the differentiation and fusion of myoblasts to form muscle fibers.
2.
Diantara tulang berikut yang merupakan tulang pipih adalah. . . .
Correct Answer
D. Tulang rusuk dan tulang dada.
Explanation
The correct answer is "Tulang rusuk dan tulang dada." This is because both the ribs and the sternum (breastbone) are flat bones. They provide protection to the organs in the chest cavity and help with breathing. The other options, such as the vertebrae and finger bones, are not flat bones.
3.
Tulang yang berfungsi untuk melindunngi rongga dada adalah. . . .
Correct Answer
D. Tulang rusuk
Explanation
The correct answer is "Tulang rusuk". The ribs are long, curved bones that form the ribcage and provide protection to the organs in the chest cavity, such as the heart and lungs. They also help in the process of respiration by expanding and contracting during breathing.
4.
Tulang rusuk terdiri atas . . . .
Correct Answer
A. 7 pasang tulang rusuk sejati
Explanation
The correct answer is 7 pasang tulang rusuk sejati. This means that the rib cage consists of 7 pairs of true ribs. True ribs are directly attached to the sternum (breastbone) by their own costal cartilage. This is in contrast to false ribs, which either attach indirectly to the sternum or do not attach to it at all. Floating ribs, on the other hand, do not attach to the sternum at all and are only connected to the vertebrae in the back.

Berikut adalah cara yang dapat kita lakukan untuk merawat tulang rangka adalah . . . .
Correct Answer
A. Duduk dengan posisi yang benar.
Explanation
One way to take care of the skeletal system is by sitting with the correct posture. This is important because sitting with proper alignment helps to maintain the natural curves of the spine, reducing the risk of developing back and neck pain. Sitting with good posture also promotes better breathing, digestion, and overall body alignment. It helps to distribute the weight evenly on the spine and reduces the strain on the muscles and ligaments. Therefore, sitting with the correct posture is crucial for maintaining the health and well-being of the skeletal system.
6.
Kelainan tulang yang menyebabkan tulang belakang membengkok kedepan dinamakan . . . .
Correct Answer
A. Lordosis

Lordosis is the correct answer because it refers to a condition where the spine curves inward at the lower back, causing a swayback appearance. This condition can be caused by various factors such as poor posture, obesity, pregnancy, or certain medical conditions. Kifosis, on the other hand, refers to a condition where the spine curves outward, causing a hunchback appearance. Skoliosis is a condition where the spine curves sideways, while osteoporosis is a condition characterized by weak and brittle bones.

These two bones work together to provide stability and mobility to the shoulder joint. The clavicle connects the shoulder to the sternum (breastbone) in the front, while the scapula sits on the back of the ribcage. Together, they form the shoulder girdle, which allows for a wide range of movements in the arm.
11.
Punggung dapat digerakkan ke muka dan kebelakang karena mempunyai . . . .
Correct Answer
A. Ruas – ruas tulang belakang
Explanation
The correct answer is "Ruas - ruas tulang belakang." The explanation for this is that the spine is made up of individual vertebrae, which are connected by joints called facet joints. These facet joints allow for movement in the spine, including flexion (moving forward) and extension (moving backward). Therefore, the ability to move the back and forth is due to the segments or joints of the spine, known as the vertebrae.

C. Otot
Explanation
Our joints can be moved with the help of muscles. Muscles are responsible for generating force and movement in the body. They attach to our bones and when they contract, they pull on the bones, allowing us to move our joints. Without the contraction of muscles, our joints would not be able to move. Therefore, muscles are essential for the movement of our joints.
