Major Functions
Sensory Input
Integration and Process (decision)
Motor Output (response)
Thinking
Movement
Internal process of physiology
Nervous Disease/Disorder
Meningitis - Infection in brain meninges
Multiple Sclerosis - Autoimmune disease that damages myelin sheath
Spinal Cord Injury - Damage to spinal cord
Alzheimer's Disease - Form of dementia associated with age
Autism - Brain disorder that makes it difficult to communicate
Cerebrovascular Accident - Occurs when blood flow to portion of brain stopped
Reflex Arc Major Parts and Functions
Interneuron
Info from sensory to motor
Motorneuron
Info from brain or spinal cord to effector
Sensory Neuron
Info from receptor to brain or spinal cord
Effector
Responds to stimulation or inhabition by motor and produces reflex or behavorial action
Receptor
Senses specific internal or external changes
Major Parts and Functions of the Brain
Cerebrum
Sensory and motor functions
Diencephalon
Processes sensory and controls homeostatic processes
Cerebellum
Muscular activity
Brain Stem
Coordinates and regulates muscular activity
Action Potential and the Nerve Impulse
Action potential passes along axon over synaptic knob
Synaptic knob membrane becomes permable to calcium and diffuse inward
With calcium, synaptic vessicles fuse to knob membrane
Release synaptic vessicles, their neurotransmitter into synaptic cleft
Peripheral Nervous System
Cranial & Spinal Nerves that connect CNS to rest of body
Somatic: CNS to Skeletal muscles and skin
Autonomic: CNS to viscera
Sypathetic:active in fight or flight
Parasympathetic: active in normal conditions
Classification of Neurons
Mterneurons
Function: Multi in CNS that links other neurons
Motor(efferent)
Function: Multi conducts impulses from CNS to effectors
Sensory(affrent)
Function: Conducts impulses from pheripheral
Connective Tissue Coverings
Epinerium
Perinerium
Endonerium
Spinal Nerves
Cervical Plexuses (C1-C4)
Brachial Plexuses (C5-T1)
Lumboscral Plexuses (L1-S4)
Neurotransmitters
Amino Acids
Neuropeptides
Acetylcholine
Central Nervous System
Brain & Spinal Cord
Integration of info and decision making
Tissues
Neurons
Function: Communicates to neurons or other tissues by electrical impluses
Structure: Cell body, dendrites, axon, and axon terminal
Neuroglia
Function: Support, nourish, protect and isolate neurons
Myelin Sheath
Compare and Contrast the Autonomic Nervous System
Autonomic: Connects CNS to viscera
Somatic: Connects CNS to skeletal
