Name the 2 types of cells in the nervous system.

Neurons (conduct impulses); Neuroglial cells or glia (do not conduct impulses)

15

What is the brain of a neuron? (circled in red)

Nucleus

15

What houses the nucleus in a neuron? (circled in red)

Soma or cell body

15

What brings impulses to the nucleus? (circled in red)

Dendrites

15

What carries impulses away from the cell body? (circled in red)

Axon

15

What is the lipid (fatty) covering on the axon? (circled in red)

Myelin sheath- speeds up impulses

15

What is name of the periodic gaps on the axon? (circled in red)

Nodes of Ranvier

15

The axon of one neuron lies next to the dendrites of another. What is the name of the space between the two neurons?

Synaptic cleft- gap between two neurons in a synapse

15

How does an impulse travel from one neuron to another?

Chemical neurotransmitters help the impulse travel across the synaptic cleft

15

Which type of neuron carries information to the CNS (brain & spinal cord)?

Sensory or afferent neurons

15

Which type of neuron carries information to the muscles, glands, and organs of the body?

Motor or efferent neurons

15

Which type of neurons are only found in the CNS and enables communication between sensory neurons, motor neurons, and the CNS?

Interneurons

15

What are the functions of neuroglial cells? (3)

Provide nutrient support, maintain homeostasis, and produce myelin sheath

15

What are the 2 divisions of the nervous system and what structures do they include?

Central Nervous System (CNS)- brain & spinal cord; Peripheral Nervous System (PNS)- nerves outside CNS (nerves that reach all parts of the body)

15

What is the mass of nerve tissue encased by the skull?

Brain

15

What is the largest section of the brain; responsible for reasoning, thought and memory? (circled in red)

Cerebrum
