Excitatory postsynaptic potential

one of four differences in those receptors? (2pts) 1) Mechanical. Thermal. or Polymodal. 2) Morphology of the peripheral ending. Sensitivity to stimulus energy. Diameter of the axon. Whether the axon has myelin or not. 3. Which transient receptor potential (TRP receptors) seem to be involved in the mechanical pain? (1pt) Mammalian TRPA1 channels seem to be involved in mechanical…

drugs with abuse potential has no identified target receptor in the brain (Stanford, 2009). Alcohol affects numerous neurotransmitter systems through its action on the membranes of neurons (Stanford, 2009). The probability of brain damage and related neurobehavioral deficits from alcohol consumption differs among individuals (Oscar–Berman & Marinkovic, 2004, Stanford 2009). Alcohol impacts several neurotransmitters in the brain disrupting the balance between inhibitory and excitatory…

Cannabis, or cannabis sativa, originated in Central Asia and has been used for its psychoactive properties for many years (Iversen, 2008, p. 6). It affects the brain of adolescents and adults differently through the binding of CB1 receptors due to distinctions in neurocognitive development. There are certain changes in gray and white matter densities, brain volume, as well as endocannabinoid concentrations. This creates aberrations in cognition and memory performance. Cannabinoid’s structures…

The knee-jerk reflex is considered a stretch reflex and is often used by physicians to test how the nervous system is functioning. The knee-jerk reflex is tested by tapping the patellar tendon with the base of a rubber hammer. This results in the leg and foot extending upward in healthy individuals. The reflex is a response to the change in shape of the patellar tendon and quadriceps muscle. It does so to prevent damage to the muscle and ultimately the maintain homeostasis. There are a series…
