Bipennate muscles consist of two rows of oblique muscle fibres, facing in opposite diagonal directions, converging on a central tendon. Bipennate muscle is stronger than both unipennate muscle and fusiform muscle, due to a larger physiological cross-sectional area. Bipennate muscle shortens less than unipennate muscle but develops greater ...
Many distinguish top/bottom from dominant/submissive by seeing top/bottom as an expression of physical power, while dominant/submissive is an expression of psychological power. In both types of relationships - top/bottom and dominant/submissive - consent, negotiations, and mutual respect and support for one another are keys to healthy dynamics.
Cable machine upright row. The upright row is performed while standing, holding a weight hanging down in the hands, by lifting it straight up to the collarbone. This is a compound exercise that also involves the trapezius, upper back, forearms, triceps, and the biceps.
The iliacus and nearby muscles. The hip flexors are (in descending order of importance to the action of flexing the hip joint): [2] Collectively known as the iliopsoas or inner hip muscles: Psoas major; Iliacus muscle; Anterior compartment of thigh. Rectus femoris (part of the quadriceps muscle group) Sartorius; One of the gluteal muscles ...
For example, a power bottom may refer to someone who takes a more dominant role while being the receptive partner. [6] In gay male sexuality, a total bottom is someone who assumes an exclusively receptive role during anal or oral intercourse. A versatile bottom is one who prefers to bottom but who tops occasionally. [7]
In strength training, rowing (or a row, usually preceded by a qualifying adjective — for instance a cable seated row, barbell upright row, dumbbell bent-over row, T-bar rows, et cetera) is an exercise where the purpose is to strengthen the muscles that draw the rower's arms toward the body (latissimus dorsi) as well as those that retract the scapulae (trapezius and rhomboids) and those that ...
The linea alba is a white, fibrous band that is made of the bilateral rectus sheaths that join at the anterior midline of the body. These enclose the rectus abdominis muscles (a pair of long, linear muscles, commonly called the “sit-up” muscles) that originate at the pubic crest and pubic symphysis, and extend the length of the body’s trunk.
The parallel muscle architecture is found in muscles where the fibers are parallel to the force-generating axis. [1] These muscles are often used for fast or extensive movements and can be measured by the anatomical cross-sectional area (ACSA). [3] Parallel muscles can be further defined into three main categories: strap, fusiform, or fan-shaped.
