Muscle Specific Hypertrophy: Biceps, Back, and Lower Body This is sub-optimal. The glutes are slow twitch dominant by a few percent, but the hamstrings are composed of a whopping 70% fast twitch fibers. The erector spinae are slow twitch dominant by around 6%. This means you should use low reps for the hamstrings, but medium to high reps for the lower back and the glutes.

- An erection begins in the brain. Physical and/or mental stimulation cause nerves in the brain to send chemical messages to nerves in the penis telling the penile blood vessels to relax so that blood can flow freely into the penis. Once in the penis, high pressure traps the blood within both corpora cavernosa.

Fast and Slow Twitch Muscle Fiber Types Each myocyte contains many myofibrils, which are strands of proteins (actin and myosin) that can grab on to each other and pull. 1  This shortens the muscle and causes muscle contraction. 2  Therefore, slow twitch fibers are great at helping athletes run marathons and bicycle for hours.

- 1 In the lower part of the back arising from the ilium, sacrum and lumbar spines is the erector spinae muscle (467/N168). 2  It has been divided and subdivided by anatomists, but functionally is one muscle mass causing extension of the vertebral column. Fascia separates true back muscles from appendicular muscles. 2  True back muscles, developed from the epaxial division of the myotome, are segmentally innnervated by dorsal rami of spinal nerves. 3  In the neck, the splenius muscle (467/N167) is the most superficial of the true back muscles (just deep to trapezius).

Erector Spinae The erector spinae (sometimes known as sacrospinalis) is often described as a group of different muscles called iliocostalis, longissimus and spinalis. Erector spinae consists of lots of small fibres which are situated very close to the spine.

What Are Fast- and Slow-Twitch Muscles? Fast-twitch muscles break down into two categories: moderate fast-twitch (type IIa) and fast-twitch (type IIb or IIx). Moderate fast-twitch muscles are thicker, quicker to contract, and wear out more rapidly than slow-twitch. Fast-twitch, the most powerful and lowest in endurance, are activated when the body nears maximum exertion.

Erector Spinae: Functional Anatomy Guide The erector spinae (erigere, to erect; spina, spine.) consists of three long, thin muscle groups running vertically up each side of the vertebral column: the iliocostalis, longissimus and spinalis.These muscles act on different segments of the vertebral column (i.e. lumbar, thoracic, cervical).emember, there are nine erector spinae muscles with attachment points at different locations along the spine. So the different muscles control the different regions of the spine. 1  The muscles that extend the lumbar spine are called lumbar erectors, or lower erectors.

Muscle of neck n vertebral column When all the erector spinae muscles contract together, they extend or hyperextend the vertebral column. the trunk, neck or head move laterally toward the contracting side. The movement is accomplished because the articular facets of the vertebrae glide on each other. Controls flexion, lateral flexion and rotation.

- Unlike slow-twitch fibers, fast twitch-fibers rely on anaerobic respiration (glycolysis alone) to produce two molecules of ATP per molecule of glucose. While much less efficient than aerobic respiration, it is ideal for rapid bursts of movement since it is not rate limited by need for oxygen.

Myoclonus Myoclonus describes a symptom and generally is not a diagnosis of a disease. It refers to sudden, involuntary jerking of a muscle or group of muscles. Myoclonic twitches or jerks usually are caused by sudden muscle contractions, called positive myoclonus, or by muscle relaxation, called negative myoclonus. Myoclonic jerks may occur alone or in sequence, in a pattern or without pattern.

Sleep spindle Sleep spindle activity has furthermore been found to be associated with the integration of new information into existing knowledge as well as directed remembering and forgetting (fast sleep spindles). During NREM sleep, the brain waves produced by people with schizophrenia lack the normal pattern of slow and fast spindles. Loss of sleep spindles are also a feature of familial fatal insomnia, a prion disease. Changes in spindle density are observed in disorders such as epilepsy and autism. Gender Differences

- It is also referred to as a contract/relax method of stretching. This is a low-grade (50 percent) stretch of the antagonist (opposite) muscle for six to 15 seconds to reduce muscle spindle activity within the agonist (prime mover) muscle.he muscle spindle’s reflex contraction of its associated muscle simultaneously causes the antagonist muscle group to relax, which is called reciprocal inhibition. The muscle spindle serves as an alert to the muscles; they are located in the muscle belly and sense muscle stretch.

- mechanoreceptors, such as the Ruffini ending, Ruffini corpuscles, and the muscle spindle/GTO complex, continue their discharge in response to a continuous stimulus. Quick-adapting mechanoreceptors are very sensitive to changes in stimulation and are, therefore, thought to mediate the sensation of joint motion. Different populations of slow-adapting mechanoreceptors are maximally stimulated at specific joint angles, and thus are thought to mediate the

Muscle Structure Fast-twitch fibers, also called FT or Type II fibers, have a quick contraction time, but are quick to fatigue. There are three different types of fast-twitch muscles. Type IIa muscle fiber has a moderately fast contraction time, and a relative long resistance to fatigue.
