major functions of nervous system
Major divisions and subdivisions of the nervous system
Major part of the brain and
their functions
Names of all the lobes and their functions
Cerebrum: is the largest part of the brain
Cerebellum: is located under the cerebrum
Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord
temporal
frontal
occipital
The central nervous system controls most functions of the body and mind
. The primary role of the Peripheral is to connect the CNS to the organs, limbs, and skin.
To collect sensory input from the body and external environment.
process and interpret the sensory input
respond appropriately to the sensory input.
parietal
processing sensory information regarding the location of parts of the body
controls important cognitive skills in humans, such as emotional expression, problem solving, memory,
involved in vision, memory, sensory input, language, emotion, and comprehension
responsible for analyzing contents, such as shapes, colors, and movement
the layers of meninges
dura mater
Arachnoid Mater
Pia Mater
thick membrane made of dense irregular connective tissue that surrounds the brain and spinal cord
thick membrane made of dense irregular connective tissue that surrounds the brain and spinal cord
collective term for the layers that cover the brain and spinal cord, lining the cranium and vertebral canal
structure and function of neurons
cell body
axon
dendrite
fibrous roots that branch out from the cell body
carries genetic information, maintains the neuron’s structure
long, tail-like structure which joins the cell body at a specialized junction
classification of neurons
motor
inter
sensory
nerve cells within the nervous system responsible for converting external stimuli
key connection between thought and motion
any neuron that acts as an intermediary in passing signals between two other neurons
major parts and functions of spinal cord
To relay messages from the brain to different parts of the body in order to perform an action
To coordinate reflexes that don't go through the brain and are managed by the spinal cord alone
To pass along messages from sensory receptors
action potential
threshold
the rising phase
the resting potential
the falling phase
recovery phase
Drugs that affect the brain
cocaine
marijuana
nicotine
reflex arch
immediate response to a particular stimulus
receive stimulation and in turn connect to other nerve cells that activate
neurological and sensory mechanism that controls a reflex,
diseases associated with the brain
Brain Cancer
mental disorders
Alzheimer's diseas
an irreversible, progressive brain disorder that slowly destroys memory and thinking skills
disease of the brain in which cancer cells
Depression, bipolar disorder, and other mood disorders
anatomy of the spinal cord
Thoracic - this region supports the ribs
Lumbar - this region is located in the lower back
Cervical - this region supports the head

autonomic nervous system.
somatic nervous system
include voluntary movement of the muscles and organs and reflex movements
control system that acts largely unconsciously and regulates bodily functions such as the heart rate
control the same group of body functions
, but they have opposite effects on the functions that they regulate

set of communicating cavities within the brain
gives a calming effect and also causes strokes
increases energy
a high that gives people a relaxing feeling
alcohol
depressant that causes memory loss
neurotransmitters
click to edit
molecules used by the nervous system to transmit messages between neurons, or from neurons to muscles
influences a neuron in one of three ways: excitatory, inhibitory or modulatory
Neurotransmitters are often referred to as the body’s chemical messengers
