Sheets of fibrous connective tissue form double-walled tubes that enclose certain tendons, notably those of the wrist and ankle.

supraspinatus, infraspinatus, teres minor, and subscapularis—the so-called SITS muscles.

rotator cuff muscles include the ___

___are found only in the PNS. Here they serve as the functional equivalent of the oligodendrocytes, supporting nerve fibers and sometimes forming a myelin sheath around them.

1. Lateral spinothalamic tracts 2. Anterior spinothalamic tracts 3. Fasciculi gracilis and cuneatus tracts 4. Spinocerebellar tracts 5. Spinotectal tracts

Five important ascending, or sensory, tracts of the spinal cord

two short roots, a ventral root (anterior root) and a dorsal root (posterior root).

Each spinal nerve attaches to the spinal cord by ___

autonomic nervous system (ANS)

The___ is a subdivision of the nervous system that regulates involuntary effectors or subconscious regulation of body functions.

1. Exteroceptors 2. Visceroceptors (or interoceptors) 3. Proprioceptors

Three groups or classes of receptors can be identified by their location:

1. Mechanoreceptors 2. Chemoreceptors 3. Thermoreceptors 4. Nociceptors 5. Photoreceptors 6. Osmoreceptors

Receptors classified into six categories based on the types of stimuli that activate them:

olfactory sensory neurons; olfactory receptor neurons

The ___, also called ___, have unique olfactory cilia that populate the surface of the olfactory epithelium lining the upper surface of the nasal cavity. They are chemoreceptors.

If synthesis of new receptors occurs faster than degradation of old receptors, the target cell will have more receptors and thus be more sensitive to the hormone.

If, on the other hand, the rate of receptor degradation exceeds the rate of receptor synthesis, the target cell’s number of receptors will decrease

If, on the other hand, the rate of receptor degradation exceeds the rate of receptor synthesis, the target cell’s number of receptors will decrease.
