Soal Latihan Biologi

The parts of the body where red blood cells are formed are:

• Skull (tengkorak)

• The ends of the bones (ujung-ujung tulang)

• Bone marrow (sumsum tulang)

• Spine (tulang belakang)

Which of the following is not a function of the skeletal system?

• forms blood cells (membuat sel darah)

• pump bloods to all parts of the body (memompa darah ke seluruh tubuh)

• reservoir for calcium and phosphorus (tempat penyimpanan Ca dan P)

• provides protection (melindungi organ tubuh)

Humans can carry out movement activities due to good cooperation between active and passive locomotion devices, namely …

• muscle and motoric nerve (otot dan saraf penggerak)

• skin and bone (kulit dan tulang)

• muscle and skin (otot dan kulit)

• muscle and bones (otot dan tulang)

The skeleton is called a passive locomotory organ because....

• needs joints so that it does not look stiff (membutuhkan sendi agar tidak terlihat kaku)

• is flexible (bersifat lentur)

• can only move if there is a command from the brain (hanya dapat bergerak jika ada perintah dari otak)

• cannot be moved if there are no muscles (tidak dapat digerakkan jika tidak ada otot)

What type of joint is found in the skull?

• pivot joint (sendi putar)

• ball-and-socket joint (sendi peluru)

• fixed joint (sendi mati)

• hinge joint (sendi engsel)

Most of the bones that make up the skull are connected to each other by fixed joints, which do not allow shifting between the bones. Which part of the skull is free enough to move?

• Maxillary bones (tulang rahang atas)

• Temporal bones (tulang pelipis)

• Mandible (tulang rahang bawah)

• Ear bones (tulang telinga)

What is a tendon?

• Connecting one muscle tissue to another (Penghubung jaringan otot yang satu dengan otot yang lain)

• Connect and bind bones to each other (Penghubung dan pengikat tulang satu dengan lainnya)

• Tissue that binds bones to joints (Jaringan pengikat tulang dengan sendi)

• Bone-to-muscle connective tissue (Jaringan pengikat tulang dengan otot)

Answer explanation

Ligaments connect bones to other bones, providing stability to joints, while tendons connect muscles to bones, enabling movement. This distinction is crucial for understanding their roles in the musculoskeletal system.
