Nervous System

Front

Brain and spinal cord; Body’s neural control center.

Back

Central Nervous System (CNS)

Front

Located outside the nervous system; Consists of nerves and sensory receptors.

Back

Peripheral Nervous System (PNS)

Front

Carries impulses from sensory receptors to the CNS.

Back

Sensory Division (afferent)

Front

Carries impulses from CNS to effectors.

Back

Motor Division (efferent)

Front

Voluntary control of skeletal muscle.

Back

Somatic Nervous System

Front

Involuntary control of cardiac muscle, smooth muscle, and glands; includes Sympathetic and Parasympathetic.

Back

Autonomic Nervous System

Front

1. Neurons - functional cells; 2. Neuroglia - supporting cells to the neurons.

Back

Types of Cells in Nervous System

Front

Dendrites, Cell bodies, Axons

Back

Parts of Neurons

Front

Several dendrites, single axon; located in CNS and PNS; motor type of message; efferent.

Back

Multipolar Neurons

Front

Two processes (Dendrites and Axon); occur in sensory portions of the eyes, ears, and nose; sensory type of message; afferent.

Back

Bipolar Neurons
