40 Cards in this Set

  • Front

  • 3rd side (hint)
These have the ability to respond to stimili and convert them into nerve impulses
Neurons
n
A synapse between a neuron and glandular cells is called;
Neuroglandular Junction
Nj
The synapse between a motor neuron and a muscle fiber is called;
Neuromuscular Junction
n
The functional contact between 2 neurons or between a neuron and an effector (muscle or gland) cell is called a
Synapse
S
The ability of a neuron to respond to a stimulus and convert it into nerve impulses is known as:
Excitability
E
Among other things a nerve impulse is sustained by the movement of sodium, potassium and other ions between the ______fluid
interstitial fluid
i
What are the 7 major structures that make up the nervous system?
Brain, Cranial nerves, Spinal cord, Spinal Nerves, Ganglia, Enteric plexus, Sensory Receptors
B,C,S,S,G,E,S
There are 12 pair of these nerves; Each follows a path and serves a special region in the body. What nerves are they?
Cranial Nerves
C
How many pairs of nerves emerge from the spinal cord to serve a specific region of the right or left side of the body
31 pairs
none
These are neurons found in walls of the organs of the gastrointestinal tract that help regulate digestion; They are an extensive network or neurons called;
Enteric Plexus
E
What are the three basic functions of the Nervous System?
Sensory function
Integrative Function
Motor Function
s,I,m
these are receptors that detect internal stimuli such as blood acidity and external stimuli(such as a rain drop landing on your arm)
Sensory Receptors
S
Afferent or Efferent?
1.Sensory neurons

2.Motor neurons
1.Afferent

2.Efferent
none
What are the neurons that carry sensory information intothe brain and spinal cord from sensory receptors
Afferent neurons (Sensory)
Sensory or ______
This Nervous System function processes sensory information by analyzing and storing some of it and by making decisions regarding appropriate response;What is this function of the NS?
Integrative Function
I
What are the neurons that serve the Integrative function? They make up the vast majority of neurons in the body
interneurons or association neurons
I
This function involves responding to integration dicisions
Motor Function
M
What neurons serve the motor function carrying information out of the brain and spinal cord to muscle fibers and glandular cells
Efferent neurons or Motor neurons
E
the cells and organs innervated by motor neurons are termed
Effectors
E
What are the two subsystems of the Nervous System?
Central Nervous System and Peripheral Nervous System
cns,pns
Define these abbreviations:
1.CNS
2.PNS
3.SNS
4.ANS
5.ENS
1.Central Nervous System
2.Peripheral Nervous System
3.Somatic Nervous System
4.Autonomic Nervous System
5.Enteric Nervous System
none
the system that consists of the brain and spinal cord which integrate and correlate many different kinds of incoming sensory information is
CNS-Central Nervous System
C
What system is the source of thoughts, emotions and memories?
CNS-Central Nervous System
c
Most nerve impulses that stimulate muscles to contract and glands to secrete originate in the;
CNS-Central Nervous System
C
All nervous tissue outside the CNS such as;cranial nerves and their branches, spinal nerves, ganglia, sensory receptors; are all part of the ________.
PNS-Peripheral Nervous System
P
The peripheral Nervous System is subdivided into 3 systems called;
SNS-Somatic Nervous System
ANS-Autonomic Nervous System
ENS-Enteric Nervous System
sns,ans,ens
Somatic Nervous System;sns; Consists of 2 types of neurons
Sensory Neurons and Motor Neurons
sn,mn
These are neurons that are a part of the SNS that convey information from somatic or special sensory receptors primarily in the head, body wall and limbs to the CNS
Sensory Neurons
SN,
These are neurons of the SNS that carry impulses from the CNS to skeletal muscles only
Motor Neurons
m
Which system contains sensory neurons that convey information from autonomic sensory recepters located primarily in the viscera (organs inside the ventral body cavity) to the CNS
ANS-Autonomic
a
Which system contains the motor neurons from the cns tht conduct nerve impulses to smooth muscle, cardiac muscle and glands.
ANS-Autonomic Nervous system
a
The Autonomic motor responses are not normally under conscious control therefore they are
Involuntary
I
The motor portion of the ANS consist of 2 branches; effectors are innervated by both and they have opposing actions ie. one increases hear rate, one decrease heart rate
Sympathetic Division (increases)
Parasympathetic (decreases)
they feel sorry
Nervous tissue consist of only two kinds of cells
Neurons and Neurolglia
n,n
The nerve cells that are responsible for most special functions attributed to the nervous system; sensing, thinking, remembering, controlling muscle activity and regulating glandular secretions.
Neurons
n
All nerve cells that support nourish and protect neurons and maintain homeostasis in the interstitial fluid that bathes neurons
Neurolgia
N
Neurolgia are also called_______. They are smaller that ________. They do not generate ______ _____.But they do multiply and divide in the mature nervous system
Glia, Neurons, Nerve impulses
none
Two of the 6 types of neurolgia are found in the PNS
Schwann cells, Satellite cells
s,s
Glial Cells do not produce nerve impulses but they can multiply and they come to the aid of neurons when damage or diseased. Name the 6 types of Glial (neurolgia) cells: A, O, M, E, S, S
