Nervous System

• The nervous system is divided into the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which includes the cranial nerves arising from the brain and the spinal nerves arising from the spinal cord .

• The autonomic nervous system (ANS) is a functional subdivision of the nervous system. The controlling centers of the ANS are located within the brain and are considered part of the CNS;

• The peripheral portions of the ANS are subdivided into the sympathetic and parasympathetic divisions.

Muscular System

• Functions:

(1) movement

(2) heat production

(3) body support and maintenance of posture

Muscle Attachment

• Skeletal muscles are attached to a bone on each end by tendons

• Tendon: composed of dense regular connective tissue

binds a muscle to the periosteum of a bone.

• When muscle contracts it shortens tension on its

tendons and attached

bones

• Insertion more movable bony attachment of the muscle

• Origin less movable attachment of the muscle
