- What are the general locations and functions of primary, secondary, and tertiary neurons in sensory pathways?arrow_forwardA neurosurgeon probes a person’s brain to map its functions. The person is awake and feels no pain during this procedure. As each area of the brain is probed, the person perceives a different sensation, as described in the table. Which structure (or lobe) of the brain is being stimulated in each scenario? [You do not need to explain why. Just state the lobe or structure] a) “I can hear a radio playing” _____________________ b) “I can see a flash of bright light” _____________________ c) “I can smell the flowers in my garden” ______________________ d) “I remember a happy moment from my childhood” ____________________ e) “I can feel pain in my foot” ____________________ f) “My finger just twitched” ____________________arrow_forwardWhat role does input from the vestibular nerve play in regulating posture (lying down, sitting up, exercising) and heart rate?arrow_forward
- Where do primary sensory neurons synapse with the secondary sensory neurons? (Human Physiology)arrow_forwardTraumatic damage to the spinal cord is common. Based on the information in Figure 2 and Table 2, is it possible that an entire column of white matter could be damaged without causing any problems with movement? Explain your answer carefully and thoroughly.arrow_forwardWhich of the following is false regarding nerve plexuses? A) Nerve plexuses occur in the cervical, brachial, lumbar and sacral regions. B) Nerve plexuses involve only the dorsal rami. C) Nerve plexuses are interlacing nerve networks, so that each branch of a plexus contains fibers from several spinal nerves. D) Because of nerve plexuses, each muscle in a limb receives its nerve supply from more than one spinal nerve. E) Because of nerve plexuses, damage to a single spinal segment or root cannot completely paralyze any limb muscle. In a spinal reflex, integration occurs in the cerebral cortex in the brain stem in the thalamus in the spinal cord in the cerebellum True or false.
