NCLEX Review Shownotes:

Understand that the Nervous system includes the Central Nervous System (CNS), the Peripheral Nervous Sytem (PNS) and the Autonomic Nervous System or the (ANS).

When I say the CENTRAL NERVOUS SYSTEM, We can simplify at as the BRAIN and the SPINAL CORD.

The PERIPHERAL NERVOUS SYSTEM on the other hand, contains the CRANIAL NERVES and the SPINAL NERVES.

• WHEN WE TALK ABOUT THE AUTONOMIC NERVOUS SYTEM, WE ARE BASICALLY TALKING ABOUT THE “SYMPATHETIC” (FIGHT OR FLIGHT) SYSTEM OR THE “PARASYMPATHETIC” SYSTEM.
• .THE BASIC COMPONENT OF THE NERVOUS SYSTEM IS THE NERVE CELL OR NEURON

NEURON

– is the primary component of the nervous system.

– it is composed of cell body (gray matter), axon and dendrites.

BRAIN  (Central Nervous System: Brain and Spinal Cord).

CEREBRUM- Outermost area (cerebral cortex) is gray matter, deeper area is composed of white matter

• TWO HEMISPHERES: LEFT AND RIGHT AND EACH HEMISPHERE IS DIVIDED INTO TWO LOBES.

FRONTAL LOBE

• PERSONALITY, BEHAVIOR
• HIGHER INTELLECTUAL FUNCTIONING
• BROCA’S AREA: (MOTOR SPEECH AREA)

PARIETAL LOBE

• POSTCENTRAL GYRUS: REGISTERS SENSATION (TOUCH, PRESSURE)
• INTEGRATES SENSORY INFORMATION

TEMPORAL LOBE

• HEARING, TASTE, SMELL (HINT: LOCATION OF EARS – CLOSE THE TEMPLES)
• WERNICKE’S AREA: SENSORY SPEECH AREA
• (UNDERSTANDING, FORMATION OF LANGUAGE)

OCCIPITAL LOBE

• VISION

Peripheral Nervous System- composed of Spinal Nerves (31)

Autonomic Nervous System- part of the Peripheral Nervous System

• REGULATES FUNCTIONS OCCURRING AUTOMATICALLY IN THE BODY.
• ANS REGULATES SMOOTH MUSCLE, CARDIAC MUSCLE AND GLANDS.

IT IS NOT NECESSARY TO KNOW EVERY PHYSIOLOGY FOR EVERY SINGLE PART OF THE BRAIN.  BUT JUST IN CASE WE END UP GETTING LOW LEVEL QUESTIONS ON THE EXAM, THEN IT IS IMPORTANT THAT WE UNDERSTAND THE BASIC CONCEPT AND FUNCTION OF EACH AREA. IT WOULD ALSO BE A GREAT IDEA TO KNOW THE CRANIAL NERVES.

Quick NCLEX Overview:

EYE AND EAR DISORDERS

GLAUCOMA

Glaucoma: there is an increased of intraocular pressure in the eye.

There are two types:

1. OPEN ANGLE GLAUCOMA OR “PRIMARY” GLAUCOMA
2. PRIMARY ANGLE GLAUCOMA.

Open angle glaucoma is slow in onset and chronic, while the primary angle glaucoma needs immediate treatment.

Open Angle Glaucoma

Bilateral

Acute Angle-closure Glaucoma

Unilateral

TREATMENT

Beta Adrenergic Blockers

Cholinergic Agents (Pilocarpine) ♣ (Make sure to know this for the NCLEX)

AVOID ANTICHOLINERGICS (Atropine)
