What structure is the neurotransmitter acetylcholine released into at the neuromuscular junction? (a) Synaptic cleft (b) Motor endplate (c) Cytoplasm of the muscle cell (d) Cisternae. Fill in the blank. In a resting muscle fiber, the ___ of the thin myofilament covers actin active sites...
(a) Starting from the release of acetylcholine by the motor neuron, what are the steps involved in muscle contraction? (b) How is contraction ended? If the calcium uptake mechanism of a skeletal muscle sarcoplasmic reticulum were impaired, what effect would this have on the muscle contraction?
Compounds that have acetylcholine inhibitor activity have been used for hundreds of years for a variety of purposes. The belladonna plant contains the chemical substance, which is an acetylcholine inhibitor. Italian ladies once applied extracts of this plant to their eyes because it caused dilation of...
Criteria for establishing a causative genetic marker are quite rigorous. In the past linkage to MH susceptibility in one or more families, was demonstrated to loci on chromosomes 1, 3, 5, 7, 17 & 19, but the only genes show...

Cholinergic receptors, on the other hand, are activated by acetylcholine, a neurotransmitter vital for muscle activation, parasympathetic nervous system responses, and certain types of brain functions, including memory and alertness. 10 There are two main types of adrenergic receptors: alpha (α) and...

What is the specific role of acetylcholine in a skeletal muscle contraction? Describe the general functions of the nervous system. Describe the structure of a neuromuscular junction and explain its role in the control of muscle function. What are the functions of somatic receptors and sensory pathwa...
Describe the sequence of events that lead to the exocytosis of acetylcholine in the synaptic cleft of a postganglionic parasympathetic neuron. Start with an exon dendritic nicotinic receptor in a terminal ganglia. Which of the following is the most likely ...
