Removing #book# who is aware of this regional variation may use it as an aid in determining the site of the skin biopsy in unknown cases and occasionally the sex of the patient. The muscles of facial expression are located in the subcutaneous tissue, originating from bone or fascia, and inserting onto the skin. For example, the fingers are distal to the shoulder while the elbow is proximal to the fingers. A fascia is a band or sheet of connective tissue, primarily collagen, beneath the skin that attaches, stabilizes, encloses, and separates muscles and other internal organs. Figure 4.  The two most common systems are: Superficial fascia is the lowermost layer of the skin in nearly all of the regions of the body, that blends with the reticular dermis layer. Within each skeletal muscle, the muscle fibers are grouped into fascicles (“bundles”) that resemble bundles of sticks.  Deep fascia is also richly supplied with sensory receptors. fas´ciae) (L.) a sheet or band of fibrous tissue such as lies deep to the skin or invests muscles and various body organs. Skeletal muscles cover the bones and give our bodies their shape. The skeletal muscle works with nerve tissue, connective tissue and vascular or blood tissue. Finally, the terms proximal and distal refer to the location of a structure nearer, or further from, the trunk or nearer/further from the point of attachment.

Skeletal muscle is also important for holding your bones in the correct position and prevents your joints from dislocating. Students identify various muscles of the face and scalp and see them in action in this animated activity. However, more recent investigations confirmed a rich presence of thin blood vessels. The deep fascia surrounds the epimysium and encloses or lines other nearby structures such as blood vessels, nerves, and the body wall. Intramuscular injection may be preferred because muscles have larger and more numerous blood vessels than subcutaneous tissue, leading to faster absorption than subcutaneous or intradermal injections. connects muscle to muscle ... just deep to the sarcolemma. Deep-lying veins are compressed by skeletal muscle, forcing … Fascia is classified by layer, as superficial fascia, deep fascia, and visceral or parietal fascia, or by its function and anatomical location. The facial muscles are just under the skin (subcutaneous) muscles that control facial expression.They generally originate from the surface of the skull bone (rarely the fascia), and insert on the skin of the face.  Fascia is classified by layer, as superficial fascia, deep fascia, and visceral or parietal fascia, or by its function and anatomical location. Skin is superficial to muscles. Likewise, the lower limbs can be divided into two segments – the leg and the thigh and these contain the fascial compartments of the leg and the fascial compartments of the thigh.

Muscles of the face and scalp produce the facial expressions that help communicate feelings, such as anger, sadness, happiness, fear, disgust, pain, and surprise. When this occurs in muscles, it is known as myositis. Since the vasoconstrictor fibres supplying the skin vessels are far less engaged in baroreceptor modulations than are those supplying the skeletal muscle vessels (LOFVING1961)14)there is a possibility of vasodilatation in the skin and, at the ( same time, of a vasocontriction in the skeletal muscles as long as the anaesthesia is not deep enough to depress the bulbar vasomotor centre also. The deep muscles develop embryologically in the back, and are thus described as intrinsic muscles. Holds the muscle together. The Integumentary System, Part 1 - Skin Deep: Crash Course A&P #6.
