Skeletal muscle attaches to our skeleton. For example, when you are standing muscles in your back and abdomen pull against each other to keep you upright.
Motor units come indifferent sizes. To understand how a muscle contracts, you need to know a bit about. Muscle structure Each myofibril is composed of many subunits lined up end-to-end. Nerve plexuses are composed of afferent and efferent fibers that arise from the merging of the anterior rami of spinal nerves and blood vessels.
Humans have 31 left—right pairs of spinal nerves, each roughly corresponding to a segment of the vertebral column: eight cervical spinal nerve pairs C1—C812 thoracic pairs T1—T12five lumbar pairs L1—L5five sacral pairs S1—S5and one coccygeal pair.
During testing, the clinician looks for muscle weakness of a particular group of muscles. Skeletal muscles have an abundant supply of blood vessels and nerves. But the primary function of the SARCOPLASMIC RETICULUM is to STORE CALCIUM IONS. An example of a fluid connective tissue is blood which is surrounded with plasma, the matrix for this type of connective tissue.

Although the brachial plexus may appear tangled, it is highly organized and predictable with little variation among people.
Alpha 2 receptor stimulation causes a decrease in cAMP and, therefore, inhibitory effects such as smooth muscle relaxation and decreased glandular secretion.
