- A.
81
- B.
90
- C.
80
- D.

- 3.
The cranium is part of the axial skeletal system
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The cranium is indeed part of the axial skeletal system. The axial skeletal system includes the bones that form the central axis of the body, such as the skull, vertebral column, and rib cage. The cranium, also known as the skull, is a vital component of the axial skeleton as it protects the brain and supports the structures of the face. Therefore, the statement "The cranium is part of the axial skeletal system" is true.Rate this question:

The function of support supports soft tissues and provides __________ for the tendons of most skeletal muscles
- A.
Landing points
- B.
Areas
- C.
Contractions
- D.
Attachments
Correct Answer
D. AttachmentsExplanation
The skeleton supports soft tissues e.g. muscles and provides attachment points for the tendons of most skeletal musclesRate this question:

- 6.
The patella assists in protecting what part of the body?
- A.
Brain
- B.
Lungs
- C.
Vertebral column
- D.
Knee
Correct Answer
D. KneeExplanation
The patella, also known as the kneecap, is a small bone located in front of the knee joint. Its primary function is to protect the knee joint and assist in the movement of the lower leg. It acts as a shield, covering the front of the knee and providing additional support and stability to the joint. Therefore, the correct answer is knee.Rate this question:

Movement is produced through an ___________
- A.
Efficient muscular system
- B.
Efficient lever system
- C.
Efficient athlete
- D.
Efficient co-ordination
Correct Answer
B. Efficient lever systemExplanation
• Most skeletal muscles attach to bones
• When they contract, they pull on bones to produce movement
• This is primarily done through an efficient lever system, which is prevalent throughout all bodily and sporting movements.Rate this question:

- 10.
What does the bone release (on demand) into the blood to ensure homeostasis is maintained?
- A.
Temperature regulators
- B.
Minerals e.g. calcium
- C.
Red bone marrow
Correct Answer
B. Minerals e.g. calciumExplanation
• Red bone marrow is present in adult bones such as the pelvis, ribs, sternum, vertebrae and at the end of long bones such as the humerus and femur. On demand, bone releases minerals e.g. calcium into the blood to maintain critical mineral balances (homeostasis) and to distribute the minerals to other parts of the body that require it.
Homeostasis refers to maintaining an equilibrium i.e. a balance through regulationRate this question:
