Anatomy and Physiology Questions and Answers
-
Meninges Middle Layer: The arachnoid mater is the middle layer of the meninges, resembling a spider web.
-
Posterior Thigh Muscles: The hamstrings are located on the posterior thigh.
-
Muscle Relaxation Trigger: Calcium being pumped back into the sarcoplasmic reticulum is responsible for muscle relaxation.
-
ACh Release Trigger: A nerve action potential triggers the release of acetylcholine (ACh) from the prejunctional membrane.
-
Cerebrospinal Fluid (CSF) Function: CSF cushions the brain, delivers nutrients, and removes waste.
-
Sphincter Muscle Description: A sphincter muscle encircles an opening.
-
Masseter Muscle Function: The masseter muscle chews food.
