The site where a motor neuron excites a skeletal muscle fiber is called the neuromuscular junction. D Smooth muscle has well developed T tubules at the site of invagination.
B Smooth muscle in contrast to skeletal muscle cannot synthesize or secrete anyconnective tissue elements.
What are the events in muscle relaxation quizlet. _____ occurs when a rested muscle is stimulated repeatedly at low frequencies allowing relaxation between contractions. A Certain smooth muscle cells can actually divide to increase their numbers. Mesangial cells are specialised cells in the kidney that make up the mesangium of the glomerulusTogether with the mesangial matrix they form the vascular pole of the renal corpuscle.
The mesangial cell population accounts for approximately 30-40 of the total cells in the glomerulus. Turns an unsecure link into an anonymous one. This activity will test your understanding of the sequence of events that occur at the neuromuscular junction.
This causes each contraction to be stronger than the previous one until the levels of tension are equal between contractions. Free anonymous URL redirection service. Mesangial cells can be categorized as either extraglomerular mesangial cells or intraglomerular.
C Smooth muscle cannot stretch as much as skeletal muscle.
