At about 6 weeks of gestation, apoptosis takes place due to a protein named sonic hedgehog, also known as SHH, which dissolves the tissue between the fingers and toes, and the webbing disappears. In some fetuses, this process does not occur completely ...
Even for other upper extremity joints – elbow and wrist, backward movement results in extension. The knee, ankle, and wrist are exceptions, where the distal end has to move in the anterior direction for it to be called extension. [13] [page needed] For the toes, flexion is curling them downward whereas extension is uncurling them or raising them.

An example of interdigital webbing on an Abah River flying frog.. In oryzomyines, a mainly South American rodent group, the marsh rice rat, Pseudoryzomys simplex, and Sigmodontomys alfari all have small webs, which do not extend to the end of the proximal phalanges, whereas Amphinectomys savamis, Lundomys molitor and the members of the genera Holochilus and Nectomys have more expansive webbing ...
the carpal region encompassing the wrist, the palmar region encompassing the palm, the digital/phalangeal region encompassing the fingers. The thumb is referred to as the pollex. The posterior view contains, from superior to inferior, the cervical region encompassing the neck, the scapular region encompassing the scapulae and the area around,
The radial nerve innervates the finger extensors and the thumb abductor; that is, the muscles that extend at the wrist and metacarpophalangeal joints (knuckles) and abduct and extend the thumb. The median nerve innervates the flexors of the wrist and digits, the abductors and opponens of the thumb, the first and second lumbricals. The ulnar ...
The median plane, also called the midsagittal plane, which divides the body into left and right. [2] [6] This passes through the head, spinal cord, navel and, in many animals, the tail. [6] The sagittal planes, also called the parasagittal planes, which are parallel to the median plane. [1]
