Glial cells- holds the neuron and provides

nourishment, insulates, repairs and

supports neural functioning.

NEURONS - the BASIC element of behavior

has nerve cells that are the basic

element of the nervous system

PARTS OF NEURONDENDRITE

Receives the messages from the other neurons.

 AXONcarries messages to other neurons.

>myelin sheath, protective coat of fat and protein

that increases velocity

NODE OF RANVIER

TERMINAL BUTTONS

>end of axon that sends messages to other neurons.

How do neurons meet?

How do neurons receive messages?

How does a person think and behave?

SYNAPSE- is the space between two neurons

where the axon of the sending neuron

communicates with the dendrite of a receivingneuron by using chemical messages

 ALL OR NON-LAW – THE NEURON IS EITHER

ON OR OFF

Resting state/action potential

Inhibitory/ excitatory message

Brain and spinal cord -  communication channel 

• Controls behavior “REFLEX” 

Kinds of neuron involved in reflexes

SENSORY/ AFFERENT

MOTOR/EFFERENT

INTERNEURONS

SOMATIC- voluntary by means of senses

 AUTONOMIC- internal such as heart, lungs etc..sympathetic- big “O”, extra energy 

parasympathetic- arousal,daily energy

BRAIN

CEREBRAL CORTEX- Left hemisphere- mind

Right hemisphere- heartconnected by Corpus Callosum

THALAMUS AND HYPOTHALAMUS

Emotions- thalamus, responsible for feelingswhile hypothalamus, responsible for the act of

feelings.

PONS- for sleep and arousal paired with reticular

formation that is responsible also with sleep,arousal and attention.

CEREBELLUM- for appropriate action

MEDULLA- involuntary actions, digestion, heart,

breathing circulation etc.

HIPPOCAMPUS- memory LOBES : FRONTAL- MOTOR AREA- controls

voluntary movement

BROCA’S area- speech

“Broca’s aphasia” 

PARIETAL- Somatosensory Association area

TEMPORAL- Auditory function

WERNICKE’S AREA- area for understanding

both speech and production of language

OCCIPITAL- visual sense
