Skeletal Structure - Types Of Bones

1. The patella assists in protecting what part of the body?

Brain

Lungs

Vertebral column

Knee

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.

2. The cranium is part of the axial skeletal system

True

False

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.

Explanation

126 make up the appendicular skeletal system. With the axial bones there are 206 in total.

10. What does the bone release (on demand) into the blood to ensure homeostasis is maintained?

Temperature regulators

Minerals e.g. calcium

Red bone marrow

• 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. The axial bones will facilitate the movement of the limbs during the golf swing.

True

False

The appendicular bones are the main limbs and girdles that facilitate movement. Axial bones are the cranium, vertebrae, sacrum and sternum.

Explanation

The appendicular bones are the main limbs and girdles that facilitate movement. Axial bones are the cranium, vertebrae, sacrum and sternum.

12. What overall body perecntage of calcium is found within human bones?

1%

89%

99%

95%

Bone tissue stores about 99% of the body’s calcium

Explanation

Bone tissue stores about 99% of the body’s calcium

13. Movement is produced through an ___________

Efficient muscular system

Efficient lever system

Efficient athlete

Efficient co-ordination

• 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.
