Nervous System Part #1
What is the Nervous System?
Master control and communication system of the body.
What is Permeability?
Is it capable of letting things pass through
What are the 3 types of muscles?
Skeletal Muscle, Cardiac Muscle, Smooth Muscle
What are joints?
Sites where 2+ bones meet
What is the definition of physiology and anatomy?
Physio: study of the body and its parts functions
Anat: study of structure and shape of body
What are the 2 Structural Classifications of the Nervous System?
Central Nervous Systems and Peripheral Nervous System
Contrast Gyri and Sulci
Gyri: elevated ridges of tissue ("twisters/hills")
Sulci: shallow grooves ("furrows/valleys")
--- is superior to the Teres Major
Posterior Deltoid
What are the two parts of the Skeletal System and their general regions?
Axial Skeleton: Oriented along the Median Longitudinal Axis
Appendicular skeleton: Oriented lateral to the Median Longitudinal Axis
What are the 4 tissue types?
Epithelial, Connective, Muscular, Nervous
What are the 3 neuron types?
Sensory Neurons, Motor Neurons, Association Neurons (Interneurons)
How can the Right Cerebral Hemisphere control movement on the left side of the body?
Cross Wiring in the Corpus Callosum
What is the order of the layers of Skeletal Muscle (inner to outer)?
MFC (Muscle Fiber Cell), Fascicle, MB (Muscle Belly), SkM (Skeletal Muscle)
What are the 4 bone groups?
Long Bone, Flat Bone, Short Bone, Irregular Bone
Define the Median Plane and Sagittal Plane.
Median: midline, dividing body in two (left and right) halves
Sagittal: longitudinal plane dividing the body into to right and left parts (not halves)
What are the three parts of the brain?
Cerebrum, Brain Stem, Cerebellum
What are the four major regions of the brain?
Cerebral Hemisphere, Diencephalon, Brain Stem, Cerebellum
What are Troponin and Tropomyosin blocking?
What are the 5 main regions of the SS (superior to inferior)?
Cervical, Thoracic, Lumbar, Sacral, Coccyx
What are the types of epithelial tissue?
Simple: Squamos, Cuboidal, Columnar, Pseudostratified
Stratified: Stratified Squamos, Transitional
What are the basic functions of each neuron type?
Sensory: transmit from receptors to other neurons
Motor: transmit to muscle/glands
Inter- carry from sensory to motor neurons
What are the steps of action potential?
Threshold, Depolarization, Repolarization, Refractory Period, Resting State
How does Skeletal Muscle have a striated appearance?
Myofilaments overlap each other in such a way that give the tissue a striated appearance.
What 5 things does the Skeletal System do/provide?
Support, Protection, Allows movement, Storage, Blood cell formation
What are the 12 systems of the body?
Skeletal, Muscular, Cardiovascular, Lymphatic, Nervous, Respiratory, Reproductive, Lymphoid/Immune, Urinary, Digestive, Endocrine, Integumentary
