The adult human skeleton typically includes 206 named bones. These bones could be grouped in two divisions: axial skeleton and appendicular skeleton.
amino acid – a protein’s monomer; contains a central carbon or alpha carbon to which an amino group, a carboxyl team, a hydrogen, and an R group or side chain is hooked up; the R group differs for all 20 frequent amino acids.
bronchial bud – structure while in the building embryo that varieties in the event the laryngotracheal bud extends and branches to variety two bulbous buildings.
cleavage – method of mitotic cell division by which the cell divides but the full quantity continues to be unchanged; this process serves to make scaled-down and scaled-down cells.
deltoid ligament – wide intrinsic ligament Situated on the medial facet from the ankle joint; supports the talus within the talocrural joint and resists excess eversion on the foot.
blood islands – masses of producing blood vessels and fashioned factors from mesodermal cells scattered through the embryonic disc.
carpal tunnel – passageway in between the anterior forearm and hand fashioned because of the carpal bones and flexor retinaculum.
basal nuclei – nuclei with the cerebrum (with a couple of elements while in the higher Mind stem and diencephalon) that are accountable for examining cortical motion instructions and comparing them with the general condition of the individual via broad modulatory exercise of dopamine neurons; mainly related to motor capabilities, as evidenced in the signs and symptoms of Parkinson’s and Huntington’s ailments.
The central nervous process lies mainly within the axial skeleton, the brain becoming perfectly safeguarded from the cranium as well as spinal cord because of the vertebral column, via the bony neural arches (the arches of bone that encircle the spinal twine) as well as intervening ligaments.
Marathon Runners Runners show two qualities of living humans—responsiveness and motion. Anatomic website constructions and physiological processes allow runners to coordinate the motion of muscle groups and sweat in response to increasing interior body temperature. more info (credit rating: Phil Roeder/flickr)

aldosterone – hormone manufactured and secreted with the adrenal cortex that stimulates sodium and fluid retention and will increase blood volume and blood pressure level.
corpus albicans – non-practical composition remaining inside the ovarian stroma pursuing structural and purposeful regression in the corpus luteum.
allantois – finger-like outpocketing of yolk sac kinds the primitive excretory duct from the embryo; precursor into the urinary bladder.
