Motor Endplate
Motor endplate is also known as terminal button. This is the specialized synapse that an alpha-motorneuron makes to all the muscle fibers (i.e. a motorunit) it innervates. Acetylcholine is secreted at the synapse that in turn depolarize the muscle fibers … Continue reading Motor Endplate
Cardiac Muscle
Cardiac muscle resembles skeletal muscle in the striations and thus also known as striated muscles. However, cardiac muscle is different in that cardiac muscle cells (cardiacmyocytes) do not fuse and thus the resulting fibers are not multinucleated. Each cardiacmyocyte are … Continue reading Cardiac Muscle
Skeletal Muscle
Skeletal muscle tissue is easily distinguished by the striation (thus also known as striated muscle). They are arranged as long cylinders and since fused from development, contain multiple nuclei within each muscle fiber/cell. Continue reading Skeletal Muscle
Muscle Spindle
Muscle spindle is a stretch receptor that is found within the belly of a muscle. It monitors how stretched that particular muscle is and initiate the stretch reflex to prevent injury caused by over-stretching and to maintain posture. Below is … Continue reading Muscle Spindle
Smooth Muscle
Also known as non-striated muscle and can be found within the walls of large blood vessels (including aorta, arteries, arterioles and veins but in different amount), trachea, lower part of esophagus, intestines and arrector pili of skin. These are involuntary … Continue reading Smooth Muscle
