function of protein during muscle contraction
Transmit motor neuron to the skeletal muscle fibre quickly and reliably, to ensure precise control of skeletal muscle contraction and therefore voluntary movement.
T-tubules are invaginations of the plasma membrane, which are present exclusively in striated muscle. their role is to maintains the SR calcium store under the tight control of membrane depolarization via the voltage sensor channel DHPR
lowering testosterone levels, follicle stimulating hormone, and luteinizing hormone, and raising estrogen levels, which reduce sperm production
shrinking the testes, which can cause impotence or infertility
changing gonadotropinTrusted Source release which impacts sperm production
causing early ejaculation or decreased ejaculation
changing the shape, size, and movement of healthy sperm
sarcoplasmic reticulum is a complex network of specialized smooth endoplasmic reticulum that is importnt in transmitting the electrical impulse as well as in the storage of calcium ions.
a suggested mechanism of contraction of striated muscles, actin and myosin filaments to be precise, which overlap each other resulting in the shortening of the muscle fibre length
regulate muscle contraction by blocking the binding of myosin to filamentous actin.

Striated muscle makes up the muscle in the body that are attached to the skeleton
striated muscle is made up of muscle fibres
A muscle fibre is a highly specialised cell like
Each muscle fibre contains an organised arrangement of contractile proteins in the cytoplasm
each muscle fibre is surrounded by a cell surface membrane
the origin and development of the sperm cells within the male reproductive organs, the testes. the testes are composed of numerous thin tightly coiled tubules known as the seminiferous tubules. the sperm cells are produced within the walls of the tubules. half of the new cells from this initial crop go on to become the future sperm cells, and the other half remain as stem cells so that there is a constant source of additional germs cells. the secondary sperm cell still must mature before it can fertilize an egg. maturation entails certain changes in the shape and form at the sperm cell
In the female reproduction system, growth process in which the primary egg cell becomes a mature ovum. some egg cells may not mature for 40 years; others degenerate and never mature. one of these two new cells is usually larger than the other and is known as the secondary ovum; the smaller cell is known as a polar body
Estrogen levels rise and fall twice during the menstrual cycle. Estrogen levels rise during the mid-follicular phase and then drop precipitously after ovulation. This is followed by a secondary rise in estrogen levels during the mid-luteal phase with a decrease at the end of the menstrual cycle.
the menstrual cycle is complex and controlled by many different glands and the hormones that these glands produce. the four phase of the menstrual cycle are menstruation, the follicular phase, ovulation and the luteal phase. common menstrual problems include heavy or painful periods and PMS
larger uterine cavity causing more endometrium (mucous lining the uterus) to shed
