About the CCC Credential. CCC stands for Certificate of Clinical Competence. The American Speech-Language-Hearing Association, or ASHA, grants the the designation to both practicing speech-language pathologists and audiologists.
the cell of a sensory receptor responds to a specific energy change in its environment and initiates a corresponding sensory input. adrenergic r's. receptors for epinephrine or norepinephrine, such as those on effector organs innervated by postganglionic adrenergic fibers of the sympathetic nervous system. Classified as Î±-adrenergic receptors, which are stimulated by norepinephrine, and Î²-adrenergic receptors, which are stimulated by epinephrine.
Nicotinic receptor activation causes the opening of the channel formed by the receptor. This increases the Na+ movement into the target cell, leading to depolarization and generation of the action potential. This rapidly developing change, termed a fast EPSP, is illustrated in Figures 4.3, and 6.2.
