What is a reflex arc made of?
'Made of' is difficult to say, but the reflex arc includes within it Sensory Nerve Fibres, Receptor Cells and Sensory Neurones. The effect of these is to bypass the normal interface with the central nervous system, so that the body responds instantly to potentially dangerous stimuli.
Where can you see adaptation of the nerve cells in the simple sensory receptor?
in the liver
What is the simplest type of sensory receptor?
Free Nerve Endings are the simplest receptors.
A cranial reflex that is often used to test the sensory function of the trigeminal nerve is the?
corneal
Where does the nerve impulse travel from the reflex arc?
The nerve impulse travels through the reflex arc. It travels from the sensor through the sensory neurone, through the spinal cord and motor neurone to the effector muscle.
What is the receptor of a reflex arc?
Sensory receptor located at the distal end of a neuron or an associated sensory structure. When stimulated it creates a receptor potential, when that reaches its threshold, it will trigger 1 or more nerve impulses in the sensory neuron.
What is a receptor nerve?
Nerve receptor is a specialized cell or nerve endings that respond to sensory stimuli.
What is the sensory receptor in the eyes What is the sensory receptor in the nose What is the sensory receptors in the tongue What is the sensory receptors in the skin?
the sensory receptors for the eyes are the cornea and the optic nerve

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.
Where can you see adaptation of the nerve cells in the simple sensory receptor?
in the liver
What is the simplest type of sensory receptor?
Free Nerve Endings are the simplest receptors.
What are sensory receptors?
A sensory receptor is a sensory nerve ending that responds to a stimulus in the internal or external environment of an organism. The sensory receptor initiates sensory transduction by creating graded potentials or action potentials in the same cell or in an adjacent one.
What are the sensory receptors for eyes and nose?
The sensory receptors for the eyes are the optic nerve and the retina. The sensory receptor for the nose are the olfactory nerves.
A cranial reflex that is often used to test the sensory function of the trigeminal nerve is the?
corneal
What is the name of the nerve cell between the receptor cell and the central nervous system?
SENSORY NEURONE
Where does the nerve impulse travel from the reflex arc?
The nerve impulse travels through the reflex arc. It travels from the sensor through the sensory neurone, through the spinal cord and motor neurone to the effector muscle.
