A reflex arc begins with the stimulation of a sensory receptor such as those on the skin. The stimulus is then passed as an electrical impulse along sensory, relay and motor neurones (by-passing the brain) before reaching an effector orgen, like a muscle, which then responds to the stimulus.
What else can I help you with?
How does effector relate to reflex arc?
An effector is a part of the body (such as a muscle or gland) that carries out the response in a reflex arc. In a reflex arc, when a stimulus is detected by a sensory receptor, a message is sent via a sensory neuron to the spinal cord, where it is processed, and then a message is sent via a motor neuron to the effector causing a response.
Milk letdown is a neuroendocrine reflex arc that requires which hormone?
Oxytocin is the hormone required for milk letdown. It is released from the pituitary gland in response to suckling or breast stimulation.
What are the 5 steps to a reflex arc?
Arrival of stimulus, Activation of a sensory neuron, Information processing by an interneuron, Activation of a motor neuron, The response by an effector. Straight out of my anatomy text book.
The sensory receptor sensory neuron motor neuron and effector involved in a reflex form a?
The sensory receptor, sensory neuron, motor neuron, and effector involved in a reflex form a reflex arc. This is a neural pathway that controls a reflex action in response to a stimulus without conscious thought.
Is the knee-jerk reflex a simple reflex stretch reflex or a spinal reflex?
The knee-jerk reflex is a type of stretch reflex, which is a type of spinal reflex. It involves the stimulation of sensory neurons in the muscle spindles of the quadriceps muscle, leading to a quick contraction of the muscle in response to a sudden stretch.
What type of neuron begins a reflex arc?
A sensory receptor is the type of neuron that begins a reflex arc.
Does A reflex arc begins with a receptor at the end of a sensory nerve?
No, a reflex arc begins with a receptor that detects a stimulus and sends a signal through a sensory nerve to the central nervous system.
How hormones function in a reflex arc?
Hormones have nothing to do in reflex arc.
Type of neurones along a reflex arc?
the sensory receptor begins then the Relay neuron and final the motor neuron
What is the pathway of reflex?
reflex arc
What are the effectors of a reflex arc?
Muscles and glands are the possible effectors of a reflex arc
What kind of reflex arc does not require an inter neuron?
A monosynaptic reflex arc does not require an interneuron. In this type of reflex arc, the sensory neuron communicates directly with the motor neuron in the spinal cord or brainstem, resulting in a quick and simple reflex response.
How does effector relate to reflex arc?
An effector is a part of the body (such as a muscle or gland) that carries out the response in a reflex arc. In a reflex arc, when a stimulus is detected by a sensory receptor, a message is sent via a sensory neuron to the spinal cord, where it is processed, and then a message is sent via a motor neuron to the effector causing a response.
Milk letdown is a neuroendocrine reflex arc that requires which hormone?
Oxytocin is the hormone required for milk letdown. It is released from the pituitary gland in response to suckling or breast stimulation.
The neural pathway of a single reflex is called?
Reflex Arc
What are the 5 steps to a reflex arc?
Arrival of stimulus, Activation of a sensory neuron, Information processing by an interneuron, Activation of a motor neuron, The response by an effector. Straight out of my anatomy text book.
After touching a hot stove you immediately withdraw your hand and step back What kind of reflex arc is involved Where are the receptors located and what is their function?
This type of reflex never in fact reaches the brain. The reflex arc begins with the perception of temperature, moves to the peripheral spinal chord, and is immediately sent back into a muscular contraction to move the hand away.
