-
· Receives
signals from neurons or sense organs
· Sensory,
Motor & Inter neurons
· Processes
signals
· Sends
signals to other neurons, muscles or organs
The Neuron
-
The brain contains _____ neurons
100 billion
-
Sensory neurons respond to input from the _____
Sense organs
-
Motor neurons send signals to ______ to control ______
muscles; movement
-
_______ stand between the neurons that register "whats out there" and those that control movement
Interneuron
-
A set of neurons that affect one another
Brain Circuit
-
________receive information from other neurons or the environment
Dendrites
-
__________ controls the cell’s metabolic activities and integrates inputs
Cell Body
-
______ release chemicals into the space between neurons when their neuron has
been triggered
Terminal buttons
-
______ conducts the nerve impulse away from the
cell body
Axon
-
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
Neurotransmitters and Neuromodulators:
-
Traditional view
· Fills
the gaps between neurons
· Supports
and feeds neurons
· Cleans
up dead neurons and extra neurotransmitters
Glial Cells
-
-Top, rear of the brain
-Functions include:
· Attention
· Spatial location
· Somatosensory processing
-Unilateral visual neglect
The Parietal Lobes:
-
in the front of the brain; animalistic like
function
Forebrain
-
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
Thalamus
-
sits under the thalamus; helps control
many body functions i.e.; body temp, heart-rate, sexual behavior, regulating
hormones, eating
Hypothalamus
-
allows people to store info in their
memory banks; role is to help us retain facts
Hippocampus
-
near the hippocampus, helps us regulate our
emotions
Amygdala
-
involved in planning and producing
movement
Basal Ganglia:
-
large structure at the base of the brain;
physical coordination, estimating time, ability to stand, keep an upright
posture, ability to pay attention
Cerebellum
