Nervous System
By Allison Merritt, Tyler Tunell
What is the Nervous System?
Made of Neurons Controls body functions and processes Divided into CNS, and PNS
Neurons
A specialized cell in the nervous system Carries neural impulses through a complex
system of neurons 3 types: Sensory, Motor, and Interneuron's
Neurons
Brain Structure/ Function
Forebrain –5 main regions: Thalamus, Hypothalamus, Amygdala, Hippocampus, and Cerebral Cortex
Hindbrain – 3 areas: Medulla, Cerebellum, and Pons
Midbrain
Brain Structure/ Function
Central Nervous System Peripheral Nervous System
Brain Structure/ Function
Anatomy and Function of Spinal Cord
Link between PNS and brain White matter Gray matter Dorsal root Ventral root Reflexes Intervertabral Disk Disease
Anatomy and Function of Spinal Cord
Sensory Somatic and Autonomic Nervous System
Somatic Autonomic Plexus Sympathetic Parasympathetic Drugs, and medications Receptors
Clinical Practice
Aids in determining location of a defect in nervous system
Tests:– Menace response– Pupillary light reflex– Classic reflex– Gag reflex– hearing
Anesthetics and diseases
block sodium ions across membrane Extremely useful Surgical purposes Ataxia-uncontrollable movement Atrophy-muscles shrink Listeriosis-infection that affects the brain
