Spinal cord injuries If the spinal cord is damaged in an accident‚ the sections below the injury will be cut off from the circuit of information to and from your brain. This means‚ all nerves - and all body parts - linked to these areas of the spinal cord will also be disconnected from your brain and will stop functioning. Well protected To minimise the risk of such an injury‚ your spinal cord is well protected: Three tough envelopes called meninges surround your spinal cord A clear fluid‚ that

baby’s appearance is adaptive. “A reflex is an inborn‚ automatic response to a particular form of stimulation.’(P.g 143) As we know‚ some reflexes have adaptive value. Reflexes help identify normal brain and nerve activity. Caroline perhaps sees her baby lie in a fencing position. One arm is extending legs‚ throwing arms outward‚ and then bringing arms in toward the body. Then Caroline has one question in mind. “Why is she so out of proportion.” Tonic neck reflex can explain this question. It can

with us for life for example blinking the eye. A newborn baby possesses certain primitive reflexes which a pediatrician will look for to assess the neurological health of the baby. These reflexes are - .The rooting reflex .The moro reflex .The bebinski reflex .The stepping reflex However‚ even the healthiest infant will not always demonstrate these reflexes when stimulated. Each child is individual and at times when a child is hungry/tired or unhappy it can be impossible to get them to co-operate

The second principle of health is that the most basic: the animal instinct is to live. In humans‚ it is typically known as the fight or flight reflex. This reflex dictates whether you will stay and fight or if you will run and flee. I think that most individuals contain the flight reflex instead of the fight reflex. I‚ however‚ have the fight reflex. Each and every time‚ I instinctively fought to protect myself. A few years back on Halloween‚ some of neighborhood kids would jump out and scare

Syncope is classified according to its suspected pathophysiology as follows: Neurally-mediated reflex syncopal syndrome referring to a reflex that‚ when triggered‚ gives rise to vasodilation and bradykardia (1) Orthostatic syncope occurring when the autonomic nervous system is incapacitated resulting in a failure of vasoconstrictor mechanisms and thereby in orthostatic

Structure: The spinal cord is a white‚ soft and cord (rope) like material running through the backbone. The internal structure of the spinal cord is much simpler and more uniform throughout its many parts than that of the brain. No matter where it is sectioned‚ it gives the same general appearance. The interior of the spinal cord looks grey because it is filled with neurons without having myelin sheath in their axons. There are thirty-one pairs of peripheral spinal nerves connected to the spinal
