Botulism is a disease that was associated to eating out of cans that had been contaminated by a deadly bacteria. It is an anaerobic bacteria (does not need oxygen to survive). What botulism does is It floods hte area with sodium O prevents the sarcoplasmic reticulum from releasing Calcium prevent the release of the neurotransmitter acetylcholine prevent the release of the neurotransmitter dopamine

Muscle spindle structures consist of:     Extrafusal muscle fibers and gamma motor neurons     Extrafusal muscle fibers and alpha motor neurons     Golgi tendon organs and gamma motor neurons     Intrafusal muscle fibers and gamma motor neurons

I'm not too sure which ones exactly apply here

histology i want to solve all parts

Acetylcholine molecules are actively transported from the axon to their receptors on the muscle membrane by special transport proteins.

The gap junction channel formed by connexin 43 in cardiac muscle has which of the following properties? OA. It links excitation and calcium release between the Sarcolemma and sarcoplasmic reticulum in skeletal muscle. OB. Is opened and closed by a gate on the intracellular side of S4 OC is composed of Hexamers. OD. Is opened and closed by positive charges on S4 OE. All of the above

What does the binding of ACh to nicotinic receptors of skeletal muscle cells directly cause? Closing of calcium channels Cross-bridge cycling O Hydrolysis of ATP O Inhibition of acetylcholinesterase O Skeletal muscle depolarization

Increased sensory discharge from muscle spindles :-a- decreases muscle toneb- increases muscle tonec- could either increase or decrease muscle tone according to the muscle affectedd- has no effect on muscle tone

Skeletal muscle cells have the ability to do all of the following EXCEPT _____.     activating other muscle cells to contract     producing force while shortening     responding to chemicals released by nerve cells     rebounding to their former length after being stretched

Which part of the lower motor neuron circuit causes muscles to contract when they are being stretched? the muscle spindle y motor neurons a motor neurons Golgi tendon organs 17 f6 fs esc
