Turbans, beards, dreadlocks now okay BY C. Army directivesigned earlier this month, spells out changes to Army Regulationthe uniform policy, for the turban, worn by male Soldiers, the under-turban; male hair worn under a turban; the hijab, which is a head scarf worn by females; and beards worn by male members. Sergeant Major Anthony J.
Paroophoron Human vestigial structures also include leftover embryological remnants that once served a function during development, such as the belly button, and analogous structures between biological sexes.
For example, men are also born with two nipples, which are not known to serve a function compared to women. However, it seems to be no accident that during the years when the child is incontinent the glans is completely clothed by the prepuce, for, deprived of this protection, the glans becomes susceptible to injury from contact with sodden clothes or napkin.

Head[ edit ] The Occipitalis Minor is a muscle in the back of the head which normally joins to the auricular muscles of the ear. In horses, it is the muscle that allows it to flick a fly off its back. Face[ edit ] In many non-human mammals, the upper lip and sinus area is associated with whiskers or vibrissae which serve a sensory function.
In humans, these whiskers do not exist but there are still sporadic cases where elements of the associated vibrissal capsular muscles or sinus hair muscles can be found. Based on histological studies of the upper lips of 20 cadavers, Tamatsu et al. It is believed that this muscle actively participated in the arboreal locomotion of primates, but currently has no function, because it does not provide more grip strength.
Anatomical studies suggest that the forces generated by the pyramidalis muscles are relatively small. One particular variant is the existence of the dorsoepitrochlearis or latissimocondyloideus muscle which is a muscle passing from the tendon of the latissimus dorsi to the long head of the triceps brachii.
It is notable due to its well developed character in other apes and monkeys, where it is an important climbing muscle, namely the dorsoepitrochlearis brachii. It has some weak functionality in moving the knee and ankle but is generally considered redundant and is often used as a source of tendon for grafts.
Tongue[ edit ] Another intriguing example of human vestigiality occurs in the tongue, specifically the chondroglossus muscle. Humans also bear some vestigial behaviors and reflexes. When placing a finger or object to the palm of an infant, it will securely grasp it.
This grasp is found to be rather strong.
The grasp is also evident in the feet too. When a baby is sitting down, its prehensile feet assume a curled-in posture, similar to that observed in an adult chimp. It has been proposed that the hiccup is an evolutionary remnant of earlier amphibian respiration.
The motor pathways that enable hiccuping form early during fetal development, before the motor pathways that enable normal lung ventilation form.
Thus, according to recapitulation theory, the hiccup is evolutionarily antecedent to modern lung respiration. Additionally, they point out that hiccups and amphibian gulping are inhibited by elevated CO2 and may be stopped by GABAB receptor agonists, illustrating a possible shared physiology and evolutionary heritage.
These proposals may explain why premature infants spend 2. Fetal intrauterine hiccups are of two types. The physiological type occurs before 28 weeks after conception and tend to last five to ten minutes.
These hiccups are part of fetal development and are associated with the myelination of the phrenic nervewhich primarily controls the thoracic diaphragm. The phylogeny hypothesis explains how the hiccup reflex might have evolved, and if there is not an explanation, it may explain hiccups as an evolutionary remnant, held-over from our amphibious ancestors.
This hypothesis has been questioned because of the existence of the afferent loop of the reflex, the fact that it does not explain the reason for glottic closure, and because the very short contraction of the hiccup is unlikely to have a significant strengthening effect on the slow-twitch muscles of respiration.We picks up hot Indonesian Porn Videos in every part of the world and adds them to its unique Indonesia video collection carefully.
