What are the two main regions of the human skeleton?
The axial skeleton and the appendicular skeleton.
What bones make up the axial skeleton?
The skull, vertebral column (spine), ribs, and sternum.
What is the function of the pectoral girdle?
It links the forelimbs (arms) to the axial skeleton and is made of the scapulas and clavicles.
What are the main functions of the vertebral column?
Protecting the spinal cord, providing attachment for ribs and girdles, supporting the body trunk, and imparting flexibility.
Name the three types of muscles in the human body.
Cardiac muscle, smooth muscle (visceral muscle), and skeletal muscle (striated muscle).
What is a synovial joint and its function?
A movable joint containing synovial fluid that allows movement in one or more planes.

What is a synovial joint and its function?
A movable joint containing synovial fluid that allows movement in one or more planes.
What are antagonistic muscles?
Pairs of muscles that produce movement in opposite directions at the same joint, such as biceps and triceps.
What is the role of synovial fluid in joints?
It supplies nutrients and acts as a lubricant to reduce friction.
What is the difference between fibrous and cartilaginous joints?
Fibrous joints permit no movement, while cartilaginous joints allow slight movement.
How do hinge joints function?
They allow movement in only one plane, usually through an angle of 180 degrees, like the elbow joint.
