Document Summary

Cutaneous region of sensation specific spinal nerve. Spinal nerve damage is assessed by testing dermatomes with pinpricks and noticing areas with no sensation. A-adrenergic receptors: promotes labor contractions, stimulates piloerection, and constricts dermal blood vessels while inhibiting intestinal motility. A1- act thru calcium ions as second messenger. Ne relaxes and dilates bronchioles (smooth muscle) Increased pulmonary airflow and stronger, faster heartbeat. Both act thru camp as a second messenger. Cn 3, 7, 9, 10 and ventral (motor) roots of s2, 3, 4. Autonomic tone: balance between sympathetic tone and parasympathetic tone. Ach: secreted by preganglionic and postganglionic fibers of parasympathetic shifts in accordance with the body"s changing needs. Cholinergic fiber: secretes ach and binds to cholinergic receptors: Named for muscarine: mushroom toxin used in their. Cardiac, smooth, and gland cells have muscarinic receptors. Ach excites intestinal smooth muscle by binding to one type of muscarinic receptor.
