Last step of a reflex arc?
PNS delivers motor response from CNS to effectors...
What is the receptor of the Achilles reflex?
Hit tendon nociceptors in tendo-achilles. It goes to the CNS by sciatic nerve, then it goes to interneurons in spinal cords S1-S2. Then it goes to Alfa motor n, tibial nerve from sciatic nerve to lead to the gastrocnemius muscle.
What type of reflex operates independently of the cns?
The simplest type of reflex that operates independently of the central nervous system is a monosynaptic reflex involving a single synapse between sensory and motor neurons in the spinal cord. This reflex arc allows for a rapid response to a stimulus without requiring input from the brain.
Which component of a reflex arc is located entirely within the central nervous system?
Many authors refer to the CNS portion of the reflex arc as the integration center.In regards to a monosynaptic reflex arc, the synapse is the only portion of the integration center.Polysynaptic reflex arcs, have multiple synapses and interneuron(s).
Which part of the CNS is made up of the midbrain pons and medulla and oblongata?
The brain stem.
Which of the following does not respond to cell-mediated immunity?
pathogens in the CNS
What is the processing center of a visceral reflex?
The processing center of a visceral reflex is typically located in the central nervous system, such as the brain or spinal cord. This is where the information from sensory receptors is integrated and a response is generated to regulate internal organ function.
A reflex pathway having only one synapse in the CNS?
Reflexes are rapid involuntary responses to a given stimuli. The reflex pathway that only has one synapse in the CNS is called the monosynaptic reflex arc.
Is the brain part of the CNS or the PNS?
part of the CNS
What is the only thing complete within the CNS from the reflex arc?
only the Interneuron
Last step of a reflex arc?
PNS delivers motor response from CNS to effectors...
What structure detects the stimulus in the reflex action?
The stimulus is detected by temperature or pain receptors in the skin. These generate impulses in sensory neurons. The impulses enter the CNS ( Central nervous system ) through a part of the spinal nerve called the Dorsal root.
What is the receptor of the Achilles reflex?
Hit tendon nociceptors in tendo-achilles. It goes to the CNS by sciatic nerve, then it goes to interneurons in spinal cords S1-S2. Then it goes to Alfa motor n, tibial nerve from sciatic nerve to lead to the gastrocnemius muscle.
The simplest level of CNS function is the?
The simplest level of CNS function is the reflex arc. It involves a sensory neuron detecting a stimulus and sending a signal to the spinal cord, which then immediately sends a signal back through a motor neuron to produce a response, without involving the brain.
What is a somatic reflex and how does it occur through the CNS?
A somatic reflex is where the body responds to stimulus. The message from the stimulus is sent through the central nervous system via the spine, and from there it travels to the brain.
What part of the CNS is part of the endocrine system?
Hypothalamus
What is the part of the CNS in the cranium?
Brain
