A stout and short muscle lying posterior to the acromiodeltoid. It lies along the lower border of the scapula, and it passes through the upper forelimb, across the upper end of muscles of the upper forelimb. It originates at the spine of the scapula and inserts at the deltoid ridge.
In anatomy, the temporalis muscle, also known as the temporal muscle, is one of the muscles of mastication (chewing). It is a broad, fan-shaped convergent muscle on each side of the head that fills the temporal fossa, superior to the zygomatic arch so it covers much of the temporal bone. [ 1 ]Temporal refers to the head's temples.
Function. The internal oblique performs two major functions. Firstly as an accessory muscle of respiration, it acts as an antagonist (opponent) to the diaphragm, helping to reduce the volume of the chest cavity during exhalation. When the diaphragm contracts, it pulls the lower wall of the chest cavity down, increasing the volume of the lungs ...
Cat righting reflex. Falling Cat – images captured in a chronophotography by Étienne-Jules Marey (shown in the journal Nature, 1894) The cat righting reflex is a cat 's innate ability to orient itself as it falls in order to land on its feet. The righting reflex begins to appear at 3–4 weeks of age, and is perfected at 6–9 weeks. [1]
The piriformis muscle (from Latin piriformis 'pear-shaped') is a flat, pyramidally-shaped muscle in the gluteal region of the lower limbs. It is one of the six muscles in the lateral rotator group . The piriformis muscle has its origin upon the front surface of the sacrum , and inserts onto the greater trochanter of the femur .
The suboccipital triangleis a region of the neckbounded by the following three muscles of the suboccipital group of muscles: Rectus capitis posterior major- above and medially. Obliquus capitis superior- above and laterally. Obliquus capitis inferior- below and laterally. (Rectus capitis posterior minor is also in this region but does not form ...
The corpus callosum (Latin for "tough body"), also callosal commissure, is a wide, thick nerve tract, consisting of a flat bundle of commissural fibers, beneath the cerebral cortex in the brain. The corpus callosum is only found in placental mammals. [ 1 ] It spans part of the longitudinal fissure, connecting the left and right cerebral ...
The Visible Human Project is an effort to create a detailed data set of cross-sectional photographs of the human body, in order to facilitate anatomy visualization applications. It is used as a tool for the progression of medical findings, in which these findings link anatomy to its audiences. [1] A male and a female cadaver were cut into thin ...
