Reflex

descending spinal cord tracts. Hemorrhages develop in the gray matter shortly after injury. This leads to hemorrhagic necrosis. Myelinated fibers become extensively damaged. (McCarron, 2001) Babinski reflex occurs in infants. The big toe extends itself when the sole of the foot is touched. The reflex goes away as the child gets older. Nociceptors are stimulated and results in motor response. The toe flexors are innervated by tibial nerve and toe extensors are innervated by deep peroneal…

2. What are two important roles of the stretch reflex? The two important roles of the stretch reflex is to detect muscle length and second to prevent injuries. 3. As a kind of tension detection device for the muscle system, what protective role do GTOs play? GTOs play an important protective role for the muscle system since…

observed, with extension of the forearm. Further, branchoradialis reflex was tested, when forearm was struck directly, about 2-3 cm above the styloid process, and +2 response with flexion and supination of the forearm observed. When quadriceps reflex (knee jerk) tested, it was struck directly, just below the patella, +2 response observed with extension of the lower leg, and palpation of contraction of the quadriceps. Achilles Reflex (ankle jerk) was tested by directly striking Achilles tendon,…

retention. Fecal incontinence is very rearly present. Decreased tendon reflexes (hyporeflexia), muscle weakness and sensory disturbance in the upper extremities are signs of grey matter lesions. Hyperreflexia (decreased ankle and knee reflex), negative cremasteric reflex, positive Babinski’s sign and sensory disturbance in the lower extremities/trunk are the signs of white matter lession.…

Eardrum is shiny and translucent with a pearly grey colouration. Light reflex is at position at 7’oclock. Malleus clearly visible Ear canal of right year presence with some redness and swelling. Tympanic membrane appears amber yellow in colour, ear drum appears to be bulging and light reflex seems to be distorted. Nasal cavity assessed; bilaterally in the nasal cavity both nasal mucosa were moist and pink in colour, no presence…

the reflex of a person is what makes them unique. In such cases, as Mary Roach from 10 Things You Didn't Know about Orgasm had said, “Kinzy interviewed a woman who could be brought to orgasm by having someone stroke her eyebrow.” The reflex of having an orgasm by just a simple act that is what makes orgasms so mysteriously interesting. Apparently, one can trigger themselves to orgasm as well by just triggering the sacral nerve root which is along the spinal cord (Roach). The sexual reflex of…

1.) Distinguish vitalism from materialism and explain the doctrine of specific energies of nerves. Vitalism is a belief that a life force or “vital force” existed that goes beyond the physical and chemical components of living organisms and in some part is self determining. These life energies are transmitted through the nervous system and were believed to be instantaneous. Opposed to vitalism, materialism states that physical reality is the only reality and that living matter can be…

During exercise, more oxygen is being consumed by the body. As such, more ATP is required by the muscles that are involved in the contracts from the exercise. This results in a greater amount of oxygen being needed in order to make the ATP to be supplied to the body for it to be used as energy. The increased consumption of ATP requires the body to release more thyroid hormone. In order for this to happen, the body must also undergo more cellular respiration in order to consumer more oxygen. The…

herniated disk, or spinal canal stenosis. The manifestation of neurogenic bladder varies depending on the site of nerve injury. Brain lesions above the level of the pons (a part of the brainstem) disrupt conscious control of the voiding reflex, but the reflex itself remains intact. This results in symptoms of frequent voiding of small volumes, and difficulties in holding the urine. Some types of brain lesions that can cause this type of neurogenic bladder are a brain tumor, stroke, and trauma.…

extension and external rotation of the hips. His head faced to the left and he was able to bring close to midline when the therapist would speak to him, however he was not able to hold it there long. Aaron’s arms stayed in flexion while in supine. Clonus reflex was observed as UE tone was being tested. His high flexor tone in UE is more involved on the right side. It was not observed him bringing his hand to his mouth. He was not given the opportunity to handle objects, or reach for things so I…
