What is the function of the neck muscles discussed in the text?

What is the name of the body part joining the head to the shoulders and chest in inland vertebrates?

Which bones fuse together as an adult for added strength and protection?

Where is the shoulder joint located in the body?

Which activity is NOT mentioned as being facilitated by the muscles of the neck?

Skeletal System

The skeletal system includes all bones and joints in the body, providing support and protection for soft tissues.
Each bone is a complex living organ made up of cells, protein fibers, and minerals.
The skeleton provides attachment points for muscles, allowing for movement at joints.
Bones produce new blood cells through red bone marrow and store calcium, iron, and energy in the form of fat.
The skeleton grows throughout childhood and provides a framework for the rest of the body to grow.

Human Skeletal System

The human skeletal system consists of 206 bones of different sizes and shapes.
Bone mass reaches maximum density around age 21.

Axial Skeleton

The axial skeleton consists of the vertebral column, rib cage, skull, and associated bones.
It provides a framework for the rest of the body.

Appendicular Skeleton

The appendicular skeleton consists of the shoulder girdle, pelvic girdle, and bones of upper and lower limbs.
It is attached to the axial skeleton.

Skull

The skull is composed of 22 bones, with 21 fused bones in adults.
In children, these bones are separate to allow for skull and brain growth.
The mandible is the only bone that is not fused.

Neck

The neck has many muscles for support and structure.
Neck muscles provide mechanisms for swallowing, speaking, yawning, and moving the head.

Shoulder

The shoulder joint is a complex joint formed by the humerus and scapula, like a ball and socket.

Thorax

The thorax is the part of the body between the neck and abdomen.
It contains the chief organs of circulation and respiration.

This quiz covers the skeletal system, including the structure and functions of bones and joints in the human body. It also explores how bones provide support, protection, and attachment points for muscles, as well as their role in producing new blood cells.
