Skeletal System

What is the main function of the skeletal system?

• Digestion of food, absorption of nutrients, and elimination of waste.

• Transmission of nerve impulses, production of hormones, and elimination of waste.

• Support, protection, and movement

• Storage of minerals, production of blood cells, and regulation of body temperature.

How many bones are there in the human body?

• 206

• 500

What are the five main types of bones in the human body?

• curved bones

• circular bones

What is the difference between compact bone and spongy bone?

• Compact bone is dense and forms the outer layer of bones, while spongy bone is less dense and found inside the compact bone.

• Compact bone is more porous and forms the outer layer of bones, while spongy bone is less porous and found inside the compact bone.

• Compact bone is found inside the spongy bone, while spongy bone forms the outer layer of bones.

• Compact bone is less dense and forms the outer layer of bones, while spongy bone is dense and found inside the compact bone.

What is the purpose of the periosteum?

• The purpose of the periosteum is to facilitate muscle movement.

• The purpose of the periosteum is to provide protection, support, and nourishment to the underlying bone tissue.

• The purpose of the periosteum is to regulate body temperature.

• The purpose of the periosteum is to store minerals and fats.

What are the three types of joints in the human body?

• fibrous joints, cartilaginous joints, and synovial joints

• fixed joints, movable joints, and semi-movable joints.

• saddle joints, gliding joints, and condyloid joints.

• ball and socket joints, hinge joints, and pivot joints.

What is the function of synovial fluid in a joint?

• To cushion the joint and absorb shock.

• To strengthen the ligaments and tendons in the joint.

• To lubricate the joint, reduce friction, and provide nutrients to the cartilage.

• To regulate the temperature of the joint.

What is the difference between a hinge joint and a ball-and-socket joint?

• A hinge joint allows movement in only one plane, while a ball-and-socket joint allows movement in multiple planes.

• A hinge joint allows for more range of motion than a ball-and-socket joint.

• A hinge joint is found in the shoulder, while a ball-and-socket joint is found in the knee.

• A hinge joint allows movement in multiple planes, while a ball-and-socket joint allows movement in only one plane.

What is the role of ligaments in joint stability?

• Ligaments provide support and limit excessive movement in joints.

• Ligaments help in the production of synovial fluid in joints.

• Ligaments are responsible for the production of red blood cells in joints.

• Ligaments provide cushioning and shock absorption in joints.

What is the significance of the axial skeleton?

• The axial skeleton is responsible for the movement of the limbs.

• The axial skeleton is involved in the production of red blood cells.

• The axial skeleton provides support and protection for the organs of the head, neck, and trunk.

• The axial skeleton helps in maintaining balance and coordination.
