Nervous system

Central processing unit that connects the other systems in the body together

Parts of nervous system

Central NS


peripheral NS


automatic NS

Central NS

Brain and spinal cord

Peripheral NS

Includes cranial and spinal nerves and ANS(autonomic NS)

Three meningies that cover the brain and spinal cord

Duramater, arachnoid, piamater

Duramater

Outer most later of spinal cord- tough and protective

Arachnoid layer

Area where blood vessels are located

Piamater

Innermost layer and most delicate layer of the meninges (directly on top of spinal cord)

Location of Cerebrospinal fluid

In sub arachnoid space (portion of animal that is examined when brain and spinal cord problems are suspected)

Cerebrospinal fluid function

Bathe and nourish cells within the brain and SC (line of communication)

Duramater


Eepidur

Outermost covering-tough and fibrous

Epidural space

Fat filled space that separates the periosteum of the vertebrae

Subdural space

Space between duramater and arachnoid

Arachnoid

Delicate membrane between the duramater and piamater

Piamater

Deepest membrane which is loosely attached to the brain and SC

Peripheral nervous system

Composed of cranial nerves, spinal nerves, autonomic nerves and ganglia

cranial nerve I

Olfactory for smell

Cranial nerve II

Optic for sight

Cranial nerve VII

Facial, control of facial muscles

Cranial nerve VIII

Auditory for ears

Cranial nerve X

Vagus -longest branches to the pharynx, larynx, trachea and esophagus

Cranial nerve XII

Hypoglossal- controls muscles in tongue

Parts of central nervous system

Telencephalon


Diencephalon


Mesencephalon


Metenecephalon


Myelencephalon

Telencephalon

Telencephalon

Contains cerebrum divided into 2 cerebral hemispheres

Cerebral cortex

Divided into lobes:


Frontal


Temporal


Parietal


Occipital

Frontal lobe

Voluntary movement

Frontal lobe

Voluntary movement

Temporal lobe

Auditory stimuli

Parietal lobe

Organizes sensation of pain, temperature, touch, position, and movement

Parietal lobe

Organizes sensation of pain, temperature, touch, position, and movement

Occipital lobe

Visual perception

Diencephalon

Thalamus-sensory impulses


Epithalamus-olfactory


Hypothalamus - controls body temp and sleep

Mesencephalon

Midbrain


Auditory, visual, and muscle control

Mesencephalon

Midbrain


Auditory, visual, and muscle control

Metencephalon

Cerebellum


Giving animal sense of balance

Myelencephalon

Contains medulla oblongata


maintains normal HR and RR

Autonomic NS

Sympathetic- increased HR, dialated pupils


Parasympathetic-relax body
