what is the nervous system? - ANSWER-it is a system containing a network of neurons and it controls body functions what is the CNS? - ANSWER-central nervous system - made up of brain and spinal cord, what is the PNS? - ANSWER-peripheral nervous system - sagittal plane - ANSWER-divides brain into right and left coronal plane (frontal) - ANSWER-divides brain into anterior and posterior axial (transverse) - ANSWER-divides brain into upper and lower what are the 2 basic cell types ...

What does the nervous system do? - ANSWER-1. controls and coordinates all body functions 2. senses and interprets information from outside the body 3. transmits info 4. integrate info 5. generate comands Parts of a neuron - ANSWER--cell body -dendrite -axon Cell body (soma) - ANSWER-integrates signal Dendrites - ANSWER-a neuron's bushy, branching extensions that receive messages and conduct impulses toward the cell body Axons - ANSWER-a part of a neuron that carries impulses a...

What two motor neurons does the CNS possess? - ANSWER-1. UMN (cerebrum) 2. LMN (brainstem, spinal cord) What is Dysarthria? - ANSWER-poor movement of the vocal tract What is Ataxia? - ANSWER-poorly coordinated movements What is Apraxia of speech? - ANSWER-errors in planning speech movements What are the three most important motor cortical areas? - ANSWER-1. Primary motor 2. Premotor 3. Supplementary motor What is the pathway of the Spinal Motor Pathway? - ANSWER-—Upper motor...

primary sensory areas of "special senses" - ANSWER--hearing -vision -taste -smell hearing sensory area - ANSWER-primary auditory cortex -located in: auditory cortex & temporal lobe vision sensory area - ANSWER-primary visual cortex -located in: visual cortex & occipital lobe taste sensory area - ANSWER-gustatory cortex -located in: insular lobe (hidden) & in inferior frontal gyrus of the frontal lobe smell sensory area - ANSWER-olfactory cortex -located in: temporal lobe ...

motor cortex - ANSWER-controls voluntary movements primary motor cortex - ANSWER--receives sensory input from the cerebellum via. thalamus -sends info. to the spinal cord & brainstem -sends info to corticospinal or corticobulbar tract premotor cortex - ANSWER-The region controlling learned motor skills. -receives input from posterior parietal & visual cortexes lesions in premotor cortex - ANSWER-cause an inability to perform purposeful coordinated actions without a presence of weakn...

cell body fxn - ANSWER-integrate signals dendrite fxn - ANSWER-receive signals axon fxn - ANSWER-conduit to send signals parts of CNS - ANSWER-brain and spinal cord parts of PNS - ANSWER-somatic and autonomic systems glial cell fxns - ANSWER-physical support, nutrient flow, nerve housekeeping astrocyte fxn and location - ANSWER-clean up local debris, provide nutrients, regulate external chemical composition, CNS oligodendroglia fxn and location - ANSWER-provide support for a...

Nervous System - ANSWER-a system consisting of the brain/spinal cord (CNS) and nerves that run along the body receives sensory input from internal/external environments, transmits information, integrates input, generates commands and outputs to motor systems Basic Structure of a Neuron - ANSWER-soma/cell body, dendrites, axon, nucleus, axon terminal Syanpse - ANSWER-the interaction/communication between two neurons (axon to dendrite) Central Nervous System - ANSWER-consists of the br...

Primary sensory areas of special senses - ANSWER-Hearing, vision, taste, smell Where in the cerebral cortex is hearing - ANSWER-primary auditory cortex, located in auditory cortex and temporal lobe Where in the cerebral cortex is vision - ANSWER-primary visual cortex, located in visual cortex and occipital lobe Where in the cerebral cortex is taste - ANSWER-gustatory cortex, located in insular lobe (hidden) and in inferior frontal gyrus of the frontal lobe Where in the cerebral corte...

What nerve is is involved in hearing and balance? - ANSWER-CN VIII (Vestibulocochlear!) What does vestibular mean? - ANSWER-Position and movement of head What is the brief anatomy of the ear (hearing & balance system)? - ANSWER-1. Outer Ear (pinna, ear canal) 2. Middle Ear (tympanic membrance, ossicles (malleus, incus, stapes)) 3. Inner Ear (Cochlea, Vestibular System) What are the parts of the Middle Ear? What is the inner ear filled with? - ANSWER-1. Tympanic Membrane 2. AIR FILLED...

Motor control structures - ANSWER-cerebrum, brainstem, spinal cord, cerebellum, thalamus, basal ganglia, motor nerves/neurons, muscle fibers Motor control overview - ANSWER-Begins with CNS, ends with muscles, CNS contains two types of neurons (upper motor neurons [cerebrum], lower motor neruons [brainstem, spinal cord]), can perform complex voluntary behavior and reflexes Spinal motor pathway - ANSWER-Upper motor neurons and lower motor neurons Spinal motor pathway upper motor neurons -...
