Exam 23: General Senses

Anatomically, each muscle spindle consists of a discrete grouping of about 5 to 10 modified muscle fibers called intrafusal fibers.

Exteroceptors are often called somatic senses.

Lamellar corpuscles are least numerous in the:

Somatic sense receptors are distributed evenly throughout the body.

In referring to proprioceptors, the terms tonic and phasic are interchangeable.

Which term is another name for a variant of a Meissner corpuscle called the bulbous corpuscle?

Which of the following is true of proprioceptors?

The receptors responsible for sensing crude and persistent touch are the:

Somatic sense receptors located in muscles and joints are called visceroceptors.

Differentiate between exteroceptors, visceroceptors, and proprioceptors.

Somatic sensory receptors are found in the:

Nociceptors can respond to intense light.

Proprioceptors are receptors for touch, pain, heat, and cold.

Touch and pressure are examples of stimuli that activate mechanoreceptors.

Sensory impulses ending in what part of the central nervous system (CNS) may affect the so-called "vital sign" reflexes?

Pain that is perceived as being superficial but actually is caused by an underlying organ is called _____ pain.

Identify the sensation or function of the following somatic sense receptors: free nerve endings, Meissner corpuscles, Krause end bulbs, Ruffini corpuscles, lamellar corpuscles, muscle spindles, and Golgi tendon receptors.

Mechanoreceptors are the simplest, most common, and most widely distributed sensory receptors.

Nociceptors serve as the primary receptor for pain.

Tactile meniscus is another name for the:
