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...

Adipose tissue vs skeletal muscle - ️️Adipose: - ~ 90% lipids, small fraction of water Skeletal: - ~75% water ~18% protein Cell membrane (plasma membrane) - ️️- double layer (lipid bilayer) with phospholipids and protein molecules inserted in them - Carbohydrates are attached to extracellular side Sphingolipid chemical composition and function - ️️- sphingosine backbone with fatty acid tail, as well as possible cholines, sugars, attached. -Longer than phospholipids - act a...
