What reflexes does the spinal cord control?

What are the spinal reflexes?

Spinal reflexes are those in which the sensory stimuli arise from receptors in muscles, joints and skin, and in which the neural circuitry responsible for the motor response is entirely contained within the spinal cord.

Does the spine control reflexes?

The spinal cord transmits nerve impulses to and from the brain and mediates several important reflexes. It also coordinates more complex motor sequences (e.g. those required for walking).

What type of reflex is a spinal reflex?

Monosynaptic reflex. The monosynaptic reflexes consist of two neurons. The first is located within the spinal ganglion. This is the sensory neuron (afferent) whose peripheral process detects the stimuli from the muscle.

Does the spinal cord mediate reflexes?

The spinal cord transmits nerve impulses to and from the brain and mediates several important reflexes. It also coordinates more complex motor sequences (e.g. those required for walking).

Do spinal reflexes involve the brain?

In higher animals, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. … Reflexes do not require involvement of the brain, although in some cases the brain can prevent reflex action. Reflex arc: The path taken by the nerve impulses in a reflex is called a reflex arc.

What is the purpose of the knee-jerk reflex?

The knee-jerk reflex, also known as the patellar reflex, is a simple reflex that causes the contraction of the quadriceps muscle when the patellar tendon is stretched.

What is the process of spinal reflex?

Introduction. Spinal cord reflexes are simple behaviors produced by central nervous system (CNS) pathways that lie entirely within the spinal cord. The sensory afferent fibers that evoke these reflexes enter the spinal cord and activate spinal motor neurons directly or through a chain of one or more spinal interneurons …

What is an example of a Monosynaptic reflex?

A simple reflex that involves transmission of information from a sensory neuron to the appropriate motor neuron across a single synapse in the spinal cord. The knee-jerk reflex action is an example of a monosynaptic reflex (see stretch reflex). Compare polysynaptic reflex.
