MUSCLE FIBERS initiation of skeletal muscle contraction - Answer 1. Events in the CNS: areas of the brain responsible for voluntary movement and the descending tracts in the spinal cord. 2. Events in neuromuscular junction: is a point of synaptic contact b/w somatic motor neurons and individual muscle fibre. 3. Excitation- contraction coupling: an AP initiated in the skeletal muscle fibre results in an increase in intracellular Ca2+. 4. Ca2+ signal 5. Contraction relaxation cycle: broken...

Characteristic of type 2b muscle fibers, EXCEPT: fatigable low capillary density high capacity for glycolysis slow contraction velocity → Type 1 muscle fibers correct answer: slow contraction velocity → Type 1 muscle fibers One of the following steps in the excitation contraction coupling is similar to both skeletal and smooth muscles: activation of myosin exposure of active sites in actin release of calcium from sarcoplasmic reticulum binding of calcium to trop...

NSG 531 Advanced Pharmacology Exam 3 Questions With Correct Answers Latest Updated 2024/2025 / Graded A+. what is the difference between cardiac myocyte action potential and that of the CNS or ANS? - ANSWER nerve cell action potential is very short cardiac action potential is much longer they are longer to have adequate filling time in order to get a good contraction for a reasonable bolus of blood the only way this can happen is if the action potential is longer this will also mean that t...
