Chapter 3 delves into the intricate mechanisms of chemical signalling by neurotransmitters and hormones within the nervous system. It begins with the basic concepts of synaptic transmission, highlighting the directionality from presynaptic to postsynaptic cells and the structural components of synapses, such as axodendritic and axosomatic synapses. The chapter further explores neurotransmitters' synthesis, release, and inactivation, noting the diverse chemical classes, including amino acids, mon...

PSB 2000 Exam 2 Questions & Answers 2024/2025 What are ionotropic receptors? - ANSWERSLigand-gated channels. Neurotransmitter (ligand) binds -> channel opens -> ions pass through -> EPSP or IPSP. What are metabotropic receptors? - ANSWERSThese receptors do not have channels. Neurotransmitter binds -> G-protein on intracellular side of receptors is activated -> activates 2nd messenger -> many effects, including open or close ion channels (->EPSP or IPSP) and intracell...

Durkat 2014 Exam 2 pg 1 #. Serotonin 5-HT2 receptors are metabotropic receptor believed to be involved in the action of hallucinogens; they might also play a role in depression and psychosis. The dose-response curves below represent drugs A, B, and C that possess affinity for 5-HT2 receptors, but differ in their intrinsic activity. Effect vs. Log D Conc graph Drug C (100% Effect with higher curve) Drug A ( Lower curve) Drug B (Flat line) Drug A possesses an intrinsic activity α of _...

What do hormones do? (Broadly) They Travel through the blood and influence the activity of other organs and glands What are the effects of hormones? (Broadly) They produce long or short term changes in different cells and organs by acting like neurotransmitters at metabotropic receptors Hormones only influence... cells that have specific target receptors for that particular hormone. What are hormones secreted by? Endocrine Glands. What are the hormone producers in the human body. Pineal...

Assess how altering the external and internal concentrations of various ions impacts equilibrium potential and the RMP - Potassium: Raising the external concentration decreases the equilibrium potential and RMP Sodium: Raising the external concentration raises the equilibrium, potential and RMP, and raising the internal concentration decreases the equilibrium potential. Chloride: Raising the external concentration decreases the equilibrium potential and RMP, and raising the internal concen...
