2.

The ________ bones protect tendons by helping them overcome compressive forces.

Explanation
The sesamoid bones are small, round bones that are located within tendons. They act as a pulley, providing a smooth surface for tendons to glide over and protecting them from excessive pressure and wear. By helping tendons overcome compressive forces, the sesamoid bones play an important role in maintaining the proper functioning of joints and facilitating movement.

3.

________ bones have more complex shapes.

Explanation
Irregular bones have more complex shapes compared to other types of bones, such as long or flat bones. These bones do not fit into any specific category and have unique and varied shapes. They often have multiple projections and irregular surfaces, which contribute to their complexity. The complexity of irregular bones allows them to fulfill specific functions in the body, such as providing protection and support in areas like the spine and face.

The ONLY ________ bones in the human skeleton are in the carpals of the wrists and the tarsals of the ankles.

Explanation
The ONLY bones in the human skeleton that are considered "short" are the carpals in the wrists and the tarsals in the ankles. These bones are classified as short because of their shape and size, which are typically cube-like or block-like. Short bones are responsible for providing stability and support to the body, allowing for precise movements and fine motor skills. They are also important for shock absorption and weight distribution.

5.

________ bone is one that is cylindrical in shape, being longer than it is wide.

Explanation
A long bone is one that is cylindrical in shape, being longer than it is wide. This means that the bone has a length that exceeds its width. Long bones are typically found in the limbs, such as the femur in the thigh or the humerus in the upper arm. They provide support and mobility to the body.

6.

Three gross functions:

A.

Support, movement, energy storage
B.

Hematopoiesis, energy storage, support
C.

Support, movement, protection

Correct Answer
C. Support, movement, protection

Explanation
The correct answer is support, movement, protection. This answer accurately identifies the three main functions of the gross functions. Support refers to the role of the skeletal system in providing structural support to the body. Movement refers to the ability of the muscular system to allow the body to move and perform various activities. Protection refers to the function of the integumentary system and other structures in protecting the internal organs from injury and external threats.
