Question 9 0.4 pts The descending pain control pathway involves inhibition of the activity in peptide by the opioid A-alpha axons ; dynorphin A-beta axons; endorphin C-fibers: enkephalin A-beta axons; endorphin

we have studied in class are involved. In or our purposes, assume that only the four pathways we have studied in class are invol al life, things would not be this simple for a couple of reasons. The injuries rarely wou cact hemisections and secondly other tracts convey some of the sensations assigned to the two acts we studied, and motor control is more than just pyramidal tract function, but also involves -rebellar activity and the "extrapyramidal" tracts that we...
Question 39 3 pts Match the pathway or tract with its best description. posterior funiculus-medial lemniscal pathway [Choose) < anterolateral pathway [Choose] < spinocerebellar pathway [Choose) < corticobulbar tract lateral corticospinal tract [Choose] (Choose] innervates axial skeletal muscles sesnory input for crude touch, pressure, pain, temperature innervates limb muscles for skilled movements innervates cranial motor nuclei 5,7,9,12 sensory input for coordination of movements and proprioception sensory input for touch, proprioception, pressure and vibration anterior corticospinal tract
The Dorsal (Posterior) White Column Fiber Tract transmits: A. voluntary commands B. subconscious commands C. temperature & pain information D. touch & proprioception information E. auditory & vestibular information
The signals that control your handwriting travel down the spinal cord in the tracts. A) spinocerebellar B) lateral vestibulospinal C) medial vestibulospinal D) Ieclospinal E) costicospinal epithelium is the most widespread epithelium in the body: A) Simple columnar B) Simple squamous C) Simple cuboidal D) Pseudostratified E) Stratified squamous In the patellar tendon reflex are, the patellar ligament is stretched, which stretches the quadriceps femoris muscle of the thigh. This reflex will cause the quadriceps femoris to and the hamstrings...
1/ Spinal cord injuries at the level of the neck block the reflexogenic pathway leading to sexual arousal of the genitals. Select one: a. False b. True 2/ The faces of healthy people are generally a little asymmetrical. Select one: a. True b. False 3/ What would happen to the release of GnRH if you removed the pituitary gland from a man? Select one: a. GnRH release would be unaffected because the pituitary doesn't release GnRH b. GnRH release would...
