Muscle and Nervous Tissue

• skeletal muscle
• cardiac muscle
• smooth muscle

• attached to bones
• striated (striped) and voluntary

• found only in the heart
• striated and involuntary

• wall of organs in gut (viscera) and wall of blood vessels
• non-striated and involuntary

• based on:
• microscopic appearance
• type
• neural control of muscle tissue

• central nervous system (CNS)
• peripheral nervous system (PNS)
• autonomic nervous system (ANS)

brain and spiral cord

peripheral nerves

sympathetic and parasympathetic nervous systems

• neurons
• neuroglial cells ("glial")

• functional unit of the nervous system
• conducts impulses from one cell to another
• major parts of a neuron include the cell body (soma), axon, and dendrites

bulbous end of a neuron that contains the cell nucleus and other organelles

long, slender projection of a neuron that conducts electrical impulses away from the soma

branched projections of a neuron that act to receive/transmit signals from other neural cells to the soma

• support cells
• several different types all working to support functions of neurons and the nervous system
