The endomysium, meaning within the muscle, is a wispy layer of areolar connective tissue that ensheaths each individual muscle fiber, or muscle cell. [1] [2] [3] It also contains capillaries and nerves. It overlies the muscle fiber's cell membrane: the sarcolemma. Endomysium is the deepest and smallest component of muscle connective tissue.
Vaginal estrogen, which includes creams, pills, rings, and inserts, is more commonly prescribed due to its lower risk. DHEA (prasterone) is a promising alternative that enhances vaginal health with minimal side effects and does not significantly alter hormone levels. [8]
The efficiency is defined as the ratio of mechanical work output to the total metabolic cost, as can be calculated from oxygen consumption. This low efficiency is the result of about 40% efficiency of generating ATP from food energy, losses in converting energy from ATP into mechanical work inside the muscle, and mechanical losses inside the ...
The level of vaginal penetration when using a G-spot vibrator depends on the woman, because women's physiology is not always the same. The effects of G-spot stimulation when using the penis or a G-spot vibrator may be enhanced by additionally stimulating other erogenous zones on a woman's body, such as the clitoris or vulva as a whole.
The unusual microscopic anatomy of a muscle cell gave rise to its terminology. The cytoplasm in a muscle cell is termed the sarcoplasm; the smooth endoplasmic reticulum of a muscle cell is termed the sarcoplasmic reticulum; and the cell membrane in a muscle cell is termed the sarcolemma. [9]
Epimysium (plural epimysia [1]) (Greek epi-for on, upon, or above + Greek mys for muscle) is the fibrous tissue envelope that surrounds muscle. [2] It is a layer of dense irregular connective tissue which ensheaths the entire muscle and protects muscles from friction against other muscles and bones. [3]
Smooth muscle alpha-actin is the predominant isoform within smooth muscle. There is also a lot of actin (mainly beta-actin) that does not take part in contraction, but that polymerizes just below the plasma membrane in the presence of a contractile stimulant and may thereby assist in mechanical tension. [8]
The studies often show different results about the body strength difference between the both sexes. Two studies, conducted in the four European Union countries, involving 2,000 participants (1,000 men and 1 000 women) concluded that females are 74 - 92% as strong as males, as many women (211 of 1,000) are still physically stronger than average men.
