Anatomy review for the nervous system - Week 12 Study Guide

Distinguish the difference between neuron, neuroglial cells, Schwann cells, neurofibrils, and astrocytes.

~neurons transmit nerve impulses: nerve cell, neuroglial cells is a neutoglaicyte; neuroglia cell, Schwann cells are any cell that covers nerve fibers, neurofibrils is a fibril in the cytoplasm of the nerve cell, astrocytes is a star shaped glial cell

What is the difference between dendrites and axons?

~an axon is the long threadlike part of the nerve cell that impulses are conducted from the cell body to other cells

What color does myelin (the lipid-protein layers that form a sheath around an axon) appear?

~it appears to be white

What are the 2 main parts of the nervous system?

~to main parts of the nervous system is Central; which is the brain and spinal cord, and the Peripheral; which is the somatic and autonomic

What are 3 functions of the nervous system?

~three functions of the nervous system are: make decisions based on information received, induces muscle gland to respond, and determine changes on the outside and inside the body

What is the junction between 2 communicating neurons called?

~a junction between to 2 communicating neurons is a synapse

What are the simplest nerve pathways called?

~the simplest pathways are the Reflex arc

Put the following in the correct sequence to identify the path a reflex arc takes: effector, sensory neuron, motor neuron, receptor, interneuron.

~receptor, sensory neuron, interneuron, motor neuron, effector

What are the membranes called that are located between the bone and soft tissue of the nervous system?

~the membranes are called meninges

There are 3 layers of membranes of the nervous system. Name them in order starting with the outer layer.

~the three layers are dura mater, arachnoid mater, and pia mater

Between what 2 layers is the CSF found?

~the CSF is found between the layers arachnoid and the pia mater

In a spinal tap,...
