Summary Introduction
Introduction:
The spinal cord is a collection of nerve tissues that arise from the brain stem. It is a site which contains many motor neurons, interneurons and complex neural circuits. It is often known as ‘nuts and bolts’ of the nervous system. It controls and enables the forces on muscles and its adaptive movements.

Students have asked these similar questions
All of the following are true concerning reflex arcs EXCEPT
A.they involve a few neurons and directly enter and immediately leave the spinal cord
B.they are used to prevent harm
C.they are subconscious and automatic
D.they only use the PNS and not the CNS
If a reflex is a limited circuit within the somatic system,why do physical and neurological exams include them totest the health of an individual?
Reflexes can be somatic (as in the knee jerk response) or visceral (as in vomiting). Given that both result in an involuntary motor response, why aren’t they both considered visceral motor?

- What are the components of a reflex arc and what is the difference between a somatic motor reflex and a visceral reflex arc?arrow_forwardDescartes' version of the reflex arc was important for understanding the brain's role in sensation, perception and reactivity. Which feature of Descartes' reflex arc is comparable to neurotransmission through motor, inter, and sensory neurons in the present day reflex circuit? A) body activity B) External stimulus C) Valvules Opening D) Nerve stimulationarrow_forwardReciprocal inhibition between reflexes depends upon all the following,except :-a- presence of inhibitory interneurons in the reflex pathwaysb- presence of excitatory interneurons in the reflex pathwaysc- presence of anion channels in membranes of the involved neuronsd- release of inhibitory transmitters which block cation channels in the reflex pathwaysarrow_forward

The right foot is pulled away from the tack because of the Golgitendon reflex.b. The left leg is extended to support the body because of the stretchreflex.c. The flexor muscles of the right thigh contract, and the extensormuscles of the right thigh relax because of reciprocal innervation.d. Extensor muscles contract in both thighs because of the crossedextensor reflexarrow_forwardInfants have a reflex called sucking reflex. One way to initiate this reflex is to touch the cheek of the infant. What is the specific reflex arc components in this reflex. What would be the classification of this reflex based on development, complexity, response and processing site. Would this be a ipsilateral or contralateral reflex?arrow_forward
- Watch this video (http://openstaxcollege.org/l/reflextest) to see how to test reflexes in the abdomen.Testing reflexes of the trunk is not commonly performedin the neurological exam, but if findings suggest a problemwith the thoracic segments of the spinal cord, a series ofsuperficial reflexes of the abdomen can localize functionto those segments. If contraction is not observed when theskin lateral to the umbilicus (belly button) is stimulated,what level of the spinal cord may be damaged?arrow_forwardSuppose a person has spinal cord damage at the cervical level. would this stop the knee-jerk reflex? How would it affect the plantar reflex? Explainarrow_forwardHorner’s syndrome is a condition that presents with changes in one eye, such as pupillary constriction and dropping of eyelids, as well as decreased sweating in the face. Why could a tumor in the thoracic cavity have an effect on these autonomic functions?arrow_forward
