the neuron pictured below, is best described as multipolar true or false, explain why the state is false : Bipolar neurons have a central cell body with two extensions true List the phases of an action potential in order 1. resting potential 2. depolarization arizarion ng condition true or false , if false explain why the statement is false: the central nervous system consists of the brain and spinal cord true name and describe what is occurring in the neurocell membrane in section 2 of the diagram. include the charge of the membrane during this phase deprivation, sodium gates are opened and the sodium floods into the axon admits the depolarization of the action potential, causing the charge voltage to go from 0 to +40 mV This part of a reflex is inside the CNS, made up of one or more synapses. integration center match the following lobes of the brain with the correct function temporal - contains sensory areas for hearing and smelling frontal- contain higher levels ex.. pariteal - receives sensory info from body receptors occipital - interprets visual input which of the following structures of the spinal cord contains the cell bodies of afferent neurons dorsal root ganglion what is true about the flexor withdrawl reflex A&d (IT DOES NOT INVOLVE INTERNEURONS & THE EFFECT OF THE REFLEX IS TO CREATE A CO-CONTRACTION OF 2 MUSCLES Label the nerves (A-C) in the figure below: A: _________________ B: _________________ C: _________________ a. lateral femoral cutaneous b- femoral nerve c. saphenous which of the following is most likely a symptom of ASL impaired ability to swallow describe the function of the parasympathetic nervous system aka the housekeeper system because it promotes all of the internal responses in the relaxed state. Parasympathetic stimulation causes the pupil of the eye to get smaller and aids the lenses of the eyes to focus on close items. it helps with the digestion of food and also helps with the beating of the heart and slowing it which of the following visual conditions is caused by damage to the abducens nerve? diplopia what is the purpose of the blood brain barrier? describe its maintenance from a cellular level it is a diffusion barrier that helps in the prevention of unneeded materials that attack the CNS by keeping the brain and spinal cord away from the general blood bank.It is composed of the gilal cells astrocytes and its pertinent for regulation to be able to keep a homestatis which aids in protecting the neurons a pt is unable to extend his left wrist or fingers. what never is most likely damaged ? radial nerve explain the main steps in the process of hearing 1.) sound waves are funneled through the external auditory Canal which causes the eardrum to vibrate
