Fundamentals of the Nervous System and Nervous Tissue
Central Nervous System
Peripheral Nervous System
Special Senses
Autonomic Nervous System
100
Sensory Input, Integration, Motor Output
What is Nervous System functions
100
reception and evaluation, integration of sensory information (smell, hearing, vision)
What is Parietal Lobe
100
Classification by Stimulus Type. Mechanoreceptors Thermoreceptors Photoreceptors Chemoreceptors Nocireceptors
What is Sensory Receptors classifications
100
Rods and Cones make up
What is Photoreceptors
100
Main integration center of the ANS activity
What is Hypothalamus
200
Nerve fibers (axons) that carry information to the CNS
What is Sensory (afferent) division
200
House pineal gland
What is Epithalamus
200
Connective tissue, blood vessels, lymphatic vessels
What is Structure of a nerve
200
Overstimulation of the motion receptors
Motion Sickness
200
decrease heart and respiratory rates, and allow for digestion and the discarding of wastes
What is Parasympathetic Tone
300
Support, Insulate, Cushion and protect neurons Cannot transmitt nerve impulses retain ability to divide
What is Neuroglia/ Glial Cells
300
formed by choroid plexus in each ventricle like blood but no red blood cells lower level in protien supplies nutrients protective fluid cushion
What is Cerebrospinal Fluid
300
function: From pons to pharynx, larynx, and abdominal and thoracic viscera
What is Cranial Nerve X: Vagus
300
Children are more likely to get an infection in this part of the ear
What is Auditory Ossicles
300
short preganglionic fibers long postganglionic fibers
What is Sympathetic Fibers
400
excitable nerve cells specialized to transmit electrical signals. Irritability Conductivity extreme longevity Amitotic High metabolic rate
What is Neurons
400
Progressive degenerative disease abnormal protein deposits symptoms: memory loss, irritability, confusion, and eventually hallucinations
What is Alzheimer's Disease
400
supplies both sensory and motor innervation to diaphragm
What is Phrenic Nerve
400
can be treated with a hearing aid problem with sound wave transmission to fluids on inner ear causes: impacted ear wax, perforated eardrum, otitis media, fussion of ossicles
What is Conduction Deafness
400
Increase GI tract activity Performs maintenance activities Conserve body energy 'D' actions BP&Heart decreases breathing decreases
What is Parasympathetic Nervous System
500
Progressive autoimmune disease that affects mostly young adults where myelin sheaths are gradually destroyed and reduced to nonfunctional hardened leasions
What is Multiple Sclerosis
500
Flaccid Paralysis Spastic Paralysis Paraplegic Quadriplegic Diaphragm
What is Spinal Cord Traumas
500
Basic functional unit of nervous system capable of receiving stimuli, integrating the information and sending out motor commands based on stimulus *unlearned and involuntary
What is Reflex
500
Low visual acuity more sensitive to light do not provide sharp images or color high concentration in retina periphery
What is Rods
500
Innervates smooth and cardiac muscle and glands make adjustments to ensure optimal support for body activities operate subconscious control have viscera as most of their effectors
What is ANS motor neurons
