The conscious perception of pain is often delayed because of the time it takes for the sensations to reach the cerebral cortex. Why would this be the case based on propagation of the axon potential?
Name the three connective tissue sheaths that surround a peripheral nerve. Which of these coverings enable regrowth of a damaged axon in the periphery?

- Discuss the function of each of the following: astrocytes, oligodendrocytes, ependymal cells, in icroglia, cranium, vertebral column, meninges, cerebrospinal fluid, and blood—brain barrier.arrow_forwardYou are observing in a Physical Therapy clinic and a patient presents with back pain. The images suggest that they have a disc herniation at the disk between L3 and L4. The PT you are working with believes that the disk is putting pressure on the spinal nerve that contains the afferent and efferent neurons that control the patellar tendon reflex. Using the appropriate anatomy and physiology, describe the afferent and efferent portions of this stretch reflex pathway, including a description of the receptor and what it responds to. If you performed a patellar tendon reflex, describe whether you would expect to see an enhanced or diminished response and explain why.arrow_forwardApplying a pressure stimulus to the fluid-filled capsule of an isolated Pacinian corpuscle causes a brief burst of action potentials in the afferent neuron, which ceases until the pressure is removed, at which time another brief burst of action potentials occurs. If an experimenter removes the capsule and applies pressure directly to the afferent neuron ending, action potentials are continuously fired during the stimulus. Explain these results in the context ofadaptation.arrow_forward

Action potential occur only when the surface of the neuron is myelinated, but graded potentials occur in both in both myelinated and non-myelinated neurons. b.) The magnitude of action potential depends on the magnitude of the stimulus, whereas graded potentials are all or none. c.) The magnitude of graded potential depends on the magnitude of the stimulus, whereas action potentials are all or none.arrow_forwardInhibitory interneurons associated with the reflex arc are turned on by glutamate.
