Controls most facial expresions

Secretion of tears& saliva 

taste 

VIII. Vestibulocochlear

auditory

Taste-senses carotid

blood pressure 

Senses aortic blodd pressure

slows heart rate

stimulates digestive

organs

Taste 

controls trapezius & sternocleidomastoid

controls swallowing 

Movements

controls tongue movements. 

It process and interprets the sensory

input and makes decisions

about what should be done at each moment.

Consists of nerves fibers that conveys impulses

to the central nervous system

fom sensory receptors

Carrries impulses from the CNS to

effector organs, the muscles and glands. 

Allows us to consciously or voluntary

control our skeletal muscle. 

Regulates events that are automatic

or involuntary, such as the activity of smooth and cardiac muscles and glands.

Autonomic Nervous System

(ANS)

 Nerve glue : Support, insulate and protect

the delicate neurons

Abundant star shaped cells,form living

barrier between capillaries and neurons. 

Spirdelike phagocytes that dispose of debris,

including dead brain cells and bacteria 

Glia cells that line the cavities of the brain

and the spinal cord.Helps circulate the

cerebrospinal fluid. 

Wrap their flat extensions tightly around

the nerves fibers producing fatty insulating 

coverings called myelin sheaths. 

Neuron process that convey incoming

message toward the cell body 

Generates nerve impulses and conduct them

away from the body cell. 

Terminals containing hundreds of tiny vesicles

or membranous sac that containg chemicals 

Tiny gap that separates the axon from

the neuron. Functional junction.

Supporting cells that wrap themselves around

the axon 

Bundle of nerves fibers running through the

CNS 

The corpus callosum connects the two

hemisphere and allows to communicate with 

one another, some of the cortical functions

are   in only one hemisphere.

Dense collections of myelinated fibers(tracts).

Neurons carrying impulses from the CNS to

the viscera amd muscles and glands. 

Fewer positve ions sitting on the inner face of

the neuron's plasma membrane. 

Rush of sodium ions changes the polarity of the

neuron's membrane at that site. 

The inside is more positive and the outside

is less positive 

The outflow of positive ions from the cell

restore the electrical conditions at the

membrane to the polarized state 

The most superior part and largest of the

three brian regions .

Deeper grooves, which separates large regions

of the brain 

Is located in the parietal lobe posterior

to the central sulcus

Is located in the posterior part of the

occipital lobe 

Anterior to the central sulcus in the

frontal lobe

Is located at the base of the

precentral gyrus.

Is located at the junction of the temporal

parietal and occipital lobes

The thalamus, hypothalamus and the

epithalamus

Means bridge and are involved in the

control of breathing. 

The most inferior part of the brain stem.

Regulates vital visceral activities.

controls heart rate, blood pressure and swallowing. 

The large cauliflowerlike projects dorsally from

under the occipital lobe. 

The thalamus is a rely station for sensory impulses

The ANS is motor subdivision of the PNS that

controls body activities automatically. Regulates cardiac muscle, smooth muscle found in the walls of visceral organs and blood vessels.

What is the function of the sympathetic division?

The sympathetic division mobilizes the body during extreme situations.
