PGS 101 Brain Review

· Receives
signals from neurons or sense organs
· Sensory,
Motor & Inter neurons
· Processes
signals
· Sends
signals to other neurons, muscles or organs

The brain contains _____ neurons

Sensory neurons respond to input from the _____

Motor neurons send signals to ______ to control ______

_______ stand between the neurons that register "whats out there" and those that control movement

A set of neurons that affect one another

________receive information from other neurons or the environment

__________ controls the cell’s metabolic activities and integrates inputs

______ release chemicals into the space between neurons when their neuron has
been triggered

______ conducts the nerve impulse away from the
cell body

Step 1:

· The
action potential reaches the end of the axon

Step 2:

· Synaptic
vesicles release neurotransmitters to the synaptic cleft

Step 3:

· Neurotransmitters
blind to receptors and the action potential is transmitted

Traditional view

· Fills
the gaps between neurons

· Supports
and feeds neurons

· Cleans
up dead neurons and extra neurotransmitters

-Top, rear of the brain
-Functions include:
· Attention
· Spatial location
· Somatosensory processing
-Unilateral visual neglect

in the front of the brain; animalistic like
function

region that receives sensory input from motor
systems and helps us pay attention; aids in sleep control; if badly damaged the
human will die even if outer parts are undamaged

sits under the thalamus; helps control
many body functions i.e.; body temp, heart-rate, sexual behavior, regulating
hormones, eating

allows people to store info in their
memory banks; role is to help us retain facts

near the hippocampus, helps us regulate our
emotions

involved in planning and producing
movement

large structure at the base of the brain;
physical coordination, estimating time, ability to stand, keep an upright
posture, ability to pay attention
