Front 8

Actin and Myosin

Front 13

Cardiac Muscle

Back 13

Striated
Involuntary
Purkinje Fibers- specialized cells present in the heart

Front 14

Nerve Tissue

Back 14

Direct and helps maintain the complex internal environment of the body
Interprets incoming stimuli and directs appropriate responses at a conscious or unconscious level
Contraction are caused by nerves with results in facial expressions and joint movements as well as secretions from glands

Front 15

Dendrites

Back 15

Cytoplasmic extensions of the neuron that receive or conduct impulses toward the cell body

Front 16

Axon

Back 16

Cytoplasmic extension of the neuron that conduct impulses away from the cell body

Cell contact or junction area that occurs between two neurons or between a neuron and its effector

Front 20

Central Nervous System

Back 20

Includes brain and spinal cord
No CT
Neuroglia- soft tissue that supports nervous tissue
Receives sensory information
Integrates outgoing motor responses that are transmitted
Cannot regenerate or repair with injury

Front 21

Peripheral Nervous System

Back 21

Nerves are associated with spinal nerves and cranial nerves as well as various other organs of the body
Schwann cells- provide structural support and nourishment, located in tightly wrapped layers of the myelin sheath

Front 22

Afferent Nerves

Back 22

Carries info or relays impulses from the periphery of the body to the brain or spinal cord

Front 23
