Question

9) Identify the FALSE statement regarding sensory receptor cells. A) A graded potential is referred to as a receptor potential. B) Sensory transduction converts stimulus energy into a receptor potential. C) Each type of sensory receptor responds only to the stimulus that defines the receptor. D) Threshold is the minimal stimulus intensity required to generate an action potential. E) Many sensory receptor cells are NOT nerve cells.

Answer 1

C) Each type of sensory receptor responds only to the stimulus that defines the receptor

Step-by-step explanation:

Neurons, specialized cells within the nervous system. These help with coordinated movement ad communication within the body through the transmission of electrical signals.

Sensory receptors are highly specialized neurons. These are able to detect various chemical and physical stimuli, and are classified by their ability to detect certain stimuli such as:

• photoreceptors
• mechanoreceptors
• chemoreceptors
• thermoreceptors

Sensory receptors respond to certain intensities of stimuli, instead of one specific stimulus. e.g. Mechanoreceptors within the skin can respond to pressure changes due to touch, but may also detect sound due to specific vibrations.
