Name Reflexes affecting BLS
- Crossed Extension Reflex
- Gag reflex
- Asymmetric tonic neck reflex
- Overflow from the brainstem
What is Crossed Extension Reflex.
A spinal reflex that occurs with a painful stimulus to a limb
creating an ipsilateral withdrawal (flexion) and an ipsilateral extention of the oposite limb.
Why does Crossed Extension reflex affect contralateral movement?
How it helps?
The crossed extension reflex is crucial for balance.
You lift a painful leg, the opposite leg extends to support your weight.
How does Crossed Extention Reflex work?
–the nonciceptive input from the injured side to motor neurons on the opposite (contralateral side),
Exciting the extensors and inhibit the flexors on that side.
Ipsilateral withdrawal is
The reflex action of pulling a body part from a harmful stimulus``
occuring on the same side of the body as the stimulus.
The spinal cord is
a crucial column of nerve tissue within the vertebral column
that extends
from the brainstem to the lower back, ``
acting as the main communication pathway between the brain and the body.
It carries sensory information to the brain and motor commands
from the brain to the body, enabling movement and sensation.
Spinal reflex is
An ipsilateral withdrawal is
(flexion)
an involuntary automatic response to an painful stimulus.
At the same time the spinal reflex creates ipsilateral extention of the
Ipsilateral extention of the opposite limb
describes
The movement where is the extention of the limb on the opposite side which is contralateral to the first limb but on the same side as the reference point.
