Exam 13: The Spinal Cord and Spinal Nerves

The nerves that supply the thigh and calf of leg emerge from the

Which layer of protective connective tissue covers a nerve and fuses with the outer menix layer?

The cell bodies of the neurons that carry information from the periphery to the spinal cord are structurally classified as [dropdown 1] and functionally classified as [dropdown 2] and their cell bodies are located in [dropdown 3]. Dropdown 1 & 2 choices: Sensory Motor Integrative Dropdown 3choices: anterior gray horn anterior root dorsal root ganglion lateral gray horn posterior gray horn

In the diagram which structure contains nerve roots that arise from the lumbar,sacral,and coccygeal region of the spinal cord?

In this diagram,where is the space that contains a buoyant liquid to form a hydraulic cushion that absorbs shock?

Name and describe the locations of the four major plexuses of spinal nerves.

In this diagram which area is continuous with the 4^th ventricle of the brain?

When the quadriceps muscle extends the lower leg in the patella reflex,what is occurring in the motor neuron to produce an action potential?

Excitation of the quadriceps femoris group and inhibition of the hamstring group is termed _______ innervation.

In a stretch reflex,[dropdown 1] detect the muscle stretch.A somatic sensory neuron sends signals to [dropdown 2] in the anterior gray horn and to inhibitory [dropdown 3] in the integrating center.This stretch reflex primary motor path would be classified as [dropdown 4].This primary pathway [dropdown 5] the effector muscle and [dropdown 6] the antagonist muscle. Dropdown 1 choices: muscle spindles tendon organs nociceptors Dropdown 2&3 choices: interneuron motor neuron Dropdown 4 choices: ipsilateral contralateral Dropdown 5 choices: and f Inhibits Excites
