1.
How many bones does the appendicular skeletal system have?
Correct Answer
B. 126
Explanation
there are 126 bones in the appendicular skeletal system
2.
How many bones are within the axial skeletal system?
Correct Answer
C. 80
Explanation
there are 80 bones within the axial skeletal system
3.
The cranium is part of the axial skeletal system
Correct Answer
A. True
Explanation
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.
4.
The following bones form the structure of the arms
Correct Answer(s)
A. Radius
B. Ulna
D. Humerus
Explanation
correct answer:
radius
ulna
humerus
5.
The function of support supports soft tissues and provides __________ for the tendons of most skeletal muscles
Correct Answer
D. Attachments
Explanation
The skeleton supports soft tissues e.g. muscles and provides attachment points for the tendons of most skeletal muscles
6.
The patella assists in protecting what part of the body?
Correct Answer
D. Knee
Explanation
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.
7.
Movement is produced through an ___________
Correct Answer
B. Efficient lever system
Explanation
• 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.
8.
What overall body perecntage of calcium is found within human bones?
Correct Answer
C. 99%
Explanation
Bone tissue stores about 99% of the body’s calcium
9.
Which type of blood cell is essential for aerobic respiration?
Correct Answer
B. Red
Explanation
Red blood cells are essential for aerobic respiration. White blood cells are the cells of the immune system
10.
What does the bone release (on demand) into the blood to ensure homeostasis is maintained?
Correct Answer
B. Minerals e.g. calcium
Explanation
• 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 regulation
11.
How many bones are part of the axial skeleton?
Correct Answer
D. 80
Explanation
The axial skeletal system is made up of 80 bones which consist of the cranium, vertebrae, sacrum ans sternum
12.
How many bones form the appendicular system?
Correct Answer
D. 126
Explanation
126 make up the appendicular skeletal system. With the axial bones there are 206 in total.
13.
The axial bones will facilitate the movement of the limbs during the golf swing.
Correct Answer
B. False
Explanation
The appendicular bones are the main limbs and girdles that facilitate movement. Axial bones are the cranium, vertebrae, sacrum and sternum.
