Neuro anatomy and physiology Exam Questions With Correct Answers

Neuro anatomy and physiology Exam Questions With Correct Answers CNS - answerbrain and spinal cord PNS - answeroutside the CNS 1.SOMATIC NERVOUS SYSTEM 2.AUTONOMIC NERVOUS SYSTEM somatic nervous system - answersend messages from the CNS to skeletal muscle(voluntary muscle) autonomic nervous system - answermit message from the CNS to the smooth muscle, cardiac muscle, and certain glands of peripheral nervous system des those peripheral nerves(both cranial and spinal) that regulate functions occuring automatically in the body; regulates smooth muscle,cardiac muscle, and glands neurons - answer structure of the nervous system r sensory or motor sensory neuron - answertransmit impules *to* the CNS motor neuron - answertransmit impulse *from* the CNS what is neuron composed off - answer body us ites dendrites - answerconduct impulse *to* the cell body and called afferent(to or toward) nerve fibers. axon - answer fiber that projects from the cell body, which is usually larger than the dendrites cts impulse*away* from the neuron, and therefore called an efferent(away from) nerve fiber EXAM STUDY MATERIALS July 30, 2024 11:26 AM synapses - answerions between the axon of one neuron to the dendrite of another neuron. ses travel along neurons, moving from one neuron to the next muscular junction - answerarea of contact between the ends of a large myelinated nerve fiber and fiber skeletal muscle neurotransmitters - answermission of an impulse from one neuron to the next to make sure that neurological impulse passes from the nerve to the muscle lcholine inephrine ine onin acetylcholine - answer a role in nerve impulse transmission s transmission of the impulse norepinephrine - answerhas an impact on maintaining arousal(awakening from a deep sleep),dreaming,and regulation of mood(e.g.,happiness,sadness) dopamine - answerrily affects motor function ved in gross subconscious movements of the skeletal muscles in emotional responses serotonin - answerinduces sleep, affects sensory perception,controls temperature, and has a role in control of mood myelin/myelinated or white nerve fibers - answer in CNS and PNS that are covered with white,waxy,fatty substance ases the rate of impulse transmission and protects and insulates the fibers covered by neurilemma neurilemma - answer to regenerate injured axons eration of nerve cells occurs only in the PNA damage in the DNS result in permanent damage(paralysis), because they do not have neurilemma and are not able to regenerate brain - answer of the largest organs w
