cardiac skeleton – (also, skeleton of your heart) reinforced connective tissue Found throughout the atrioventricular septum; involves four rings that surround the openings between the atria and ventricles, plus the openings towards the pulmonary trunk and aorta; The purpose of attachment for that heart valves.
capsaicin – molecule that activates nociceptors by interacting that has a temperature-delicate ion channel which is The idea for “scorching” sensations in spicy food stuff.
codon – consecutive sequence of three nucleotides on an mRNA molecule that corresponds to a specific amino acid.
diploë – layer of spongy bone, that's sandwiched between two the layers of compact bone present in flat bones.
Hence, the motions from the body and its parts, every one of the way with the lunge of your soccer participant towards the fragile manipulations of the handicraft artist or of using difficult devices by a scientist, are made probable by individual and unique engineering preparations among muscle mass and bone.
crista galli – compact upward projection Positioned in the midline in the ground with the anterior cranial fossa; formed via the ethmoid bone.
anterior tibial artery – branches from the popliteal artery; materials blood towards the anterior tibial region; will become the dorsalis pedis artery.
Bachmann’s bundle – (also, interatrial band) group of specialised conducting cells that transmit the impulse directly from the SA node in the ideal atrium into the left atrium.
Cells, one example is, Possess a cell membrane (also known as the plasma membrane) that retains the intracellular ecosystem—the fluids and organelles—independent from your human anatomy & physiology extracellular natural environment. Blood vessels retain blood inside of a shut circulatory program, and nerves and muscles are wrapped in connective tissue sheaths that individual them from surrounding constructions.
anterior inferior iliac spine – modest, bony projection located on the anterior margin with the ilium, down below the anterior exceptional iliac backbone.
amniotic cavity – cavity that opens among the interior cell mass along with the trophoblast; develops into amnion.
cardiac plexus – paired complicated network of nerve fibres near the foundation in the heart that acquire sympathetic and parasympathetic stimulations to regulate HR.
descending aorta – percentage of the aorta that proceeds downward previous the tip of the aortic arch; subdivided into your thoracic aorta plus the abdominal aorta.
basement membrane – in human anatomy definition epithelial tissue, a skinny layer of fibrous product that anchors the epithelial tissue on the underlying connective tissue; manufactured up from the basal lamina and reticular lamina.
