Communication within the neuron
through the action potential
-
communication between neurons
action potential reaches the axon terminal, stimulates the release of neurotransmitters into the synapse
-
neurons
transmit info throughout the body
-
glial cells
provide structural, nutritional and other support for neurons
-
dendrites
DETECT signals from other neurons, sends impulses through the body
-
Cell body
integrates incoming information
-
axon
carries info from cell body to other neurons
-
myelin sheath
speeds up action potential
-
frontal lobes of brain
coordinates messages from toher lobes and regulates motor control, speech prodction, and higher functions(thinking, personality..)
-
parietal lobes
sensory processing
-
temporal lobes
hearing, language comprohension, memory, emotional control
-
Hindbrain
- major section of brain
- lower level fucntions and structures
- medulla, cerebellum, pons
-
midbrain
middle of the brain
-
forebrain
higher level functions and structures
-
what does the forebrain consist of?
- thalamus
- hypothalamus
- limbic system
- cerebral cortex
-
corpus callosum
transfers neural impulses between the brain's left and right hemispheres
-
chemical messengers (2)
- neurotransmitters
- hormones
