Sense of Touch/Feeling The Skin Senses Consider the skin has remarkable versatility: It protects us against surface injury‚ holds in body fluids‚ and helps regulate body temperature. The skin also contains nerve endings that‚ when stimulated‚ produce sensations of touch‚ pain‚ warmth and cold. Like several other senses‚ these skin senses are connected to the somatosensory cortex located in the brain’s parietal lobes. The Somatosensory Cortex The skin’s sensitivity

Adrenergic medications affect the four receptors‚ a1‚ a2‚ B1 and B2. The sympathetic nervous system triggers the secretion of epinephrine and norepinephrine. Epinephrine is a hormone and norepinephrine functions as a hormone and neurotransmitter. First we will take a look at the Alpha 1 receptors. These Alpha 1 receptors cause vasoconstriction of vascular smooth muscles. They are located on the post synaptic membranes of effector organs‚ such as on gastral and urinary sphincters. Some are located
