-
Are shorter in length in transverse section. Also exhibit branching, which gives individual ___ muscle fibers a "stair step" appearance. 50-100 um long and has a diameter of about 14 um
cardiac muscle
-
spindle shaped (thickest in the middle and tapering at both ends), non striated fibers with with one centrally located nucleus; involuntary control
smooth muscle
-
Long, cylindrical, striated fibers with many peripherally located nuclei; voluntary control.
skeletal muscle
-
the motor neuron forms a flat branching plate called a 'motor end plate. The myelin sheath stops just short of the branching presynaptic terminal.
Neuromuscular junction
-
branched striated fibers with one or two centrally located nuclei; contains interrelated disc; involuntary control.
cardiac muscle
-
location/function of cardiac muscle
heart wall; pumps blood into all parts of the body
-
cells that contain a single central nucleus. The cells stick together and are connected by specialised cell junctions, called gap junctions.The cells are spindle shaped, and the nucleus is central.
smooth muscle
-
Iris of the eye, walls of the hollow internal structures such as blood vessels, airways to the lungs, stomach, intestines, gallbladder, urinary bladder, and uterus; function?
smooth muscle (location),motion
-
Motion, posture, heat production, and protection
function of skeletal muscle
-
usually attached to bones by tendons
location of skeletal muscle
-
moves joints by strong and rapid contractions.Each muscle is a bundle of muscle fibres, each of which is a long multinucleated cell.
