Nervous System Anatomy

_____ neurons carry  messages away from the central nervous system.

• Motor

• Inter

• Sensory

• Flower

Part of the peripheral that controls conscious activities

• autonomic

• somatic

• sympathetic

• parasympathetic

Controls automatic functions like breathing, heart rate, body temperature, wake and sleep cycles, etc.

• cerebrum

• cerebellum

• basal ganglia

• brainstem

Chemicals in the neuron that help send messages

• dendrites

• neurotransmitters

• axon terminals

• vesicles

What tissue is not innervated by the autonomic nervous system?

• Glands

• Skeletal Muscle

• Cardiac Muscle

• Smooth Muscle

In a neuron, cell processes that receive information and carry it to the cell body are called

• Dendrites

• Axons

• Cell bodies

• Nissl bodies

Axons

• May branch at their ends to form collateral axons.

• Appear as single processes from each neuron.

• Are often surrounded by a myelin sheath.

• Carry action potentials away from the cell body.

• All of the above.

The two major anatomical divisions of the nervous system are the

• Central nervous system (CNS) and the peripheral nervous system (PNS).

• Somatic nervous system (SNS) and the autonomic nervous system (ANS).

• Neurons and neuroglia.

• Efferent division and the afferent division.

• None of the above.

Central Nervous System (CNS)

• Consists of the brain and spinal cord.

• Division of the PNS that transmits action potentials from sensory organs to CNS.

• Efferent subdivision that transmits impulses from CNS to skeletal muscle.

• Consists of nerves, receptors, ganglia, and synapses outside the CNS.

• Efferent subdivision that transmits impulses from the CNS to smooth muscle, cardiac muscle and Glands.

Peripheral Nervous System (PNS)

• Consists of the brain and spinal cord.

• Division of the PNS that transmits action potentials from sensory organs to CNS.

• Efferent subdivision that transmits impulses from CNS to skeletal muscle.

• Consists of nerves, receptors, ganglia, and synapses outside the CNS.

• Efferent subdivision that transmits impulses from the CNS to smooth muscle, cardiac muscle and Glands.
