Indicate whether the statement is true or false The distribution of hair follicles in follicular units bundle that attaches to the bulge region of the follicle and ex- was only present above the insertions of the arrector pili mus- tends to its superior attachment in the upper dermis. The contraction of the muscle is therefore involuntary - stresses such as cold, fear etc. What muscle tissue: *located in the walls of hollow organs *forces fluids and other substances through internal body channels *contractions are slow and sustained *dilates and constricts pupils/forms arrector pili muscle Because it can be controlled by thought, skeletal muscle is also called voluntary muscle. - Muscle cells are surrounded by endomysium ( connective tissue) and blood capillaries. Hair follicles in the scalp are grouped, forming well-defined anatomic structures known as follicular units, which are composed of terminal and vellus hairs, the associated sebaceous glands, and the arrector pili muscles.

Smooth muscle, neither striated in structure nor under voluntary control, is found within the walls of organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, urethra, bladder, blood vessels, and the arrector pili in the skin (in which it controls erection of body hair). Smooth muscle, or involuntary muscle, is found within the walls of organs and structures such as the esophagus, stomach, intestines, bronchi, uterus, urethra, bladder, blood vessels, and the arrector pili in the skin, in which it controls the erection of body hair. The arrector pili muscle is located in the dermis, the middle layer of skin, and extends along the dermal root sheath. In order to generate heat when the body is cold, the arrector pili muscles contract all at once, causing the hair to "stand up straight" on the skin.

State Tue or False and justify your answer. In the present study we ... Tissue-Tek O.C.T. - Intercalated disks-junctional complexes between adjacent cardiac muscle cells. The small hair on your body ordinarily grows at a certain angle from the skin. Each cell must be separately stimulated by nerves of the autonomic nervous system in order to contract. The arrector pili muscle, which is a band of smooth muscle that connects the hair follicle to connective tissue, contracts and creates the goose bumps on skin. Each muscle cell is filled with parallel actin and myosin filaments. The epidermis is composed of what type of epithelium? Medical definition of arrector pili muscle: one of the small fan-shaped smooth muscles associated with the base of each hair that contract when the body surface is chilled and erect the hairs, compress an oil gland above each muscle, and produce the appearance of goose bumps —called also erector pili muscle, pilomotor muscle. Hence the word "skeletal". Ch10 muscle tissue 1. Responsible for the movement of materials within and throughout the body.
