appendicular skeleton – all bones with the higher and reduced limbs, furthermore the girdle bones that attach Each and every limb for the axial skeleton.
dense body – sarcoplasmic structure that attaches to the sarcolemma and shortens the muscle mass as slim filaments slide past thick filaments.

deep femoral artery – branch with the femoral artery; offers increase on the lateral circumflex arteries.
carotid sinuses – small pockets near the base of The inner carotid arteries which are the spots on the baroreceptors and chemoreceptors that set off a reflex that aids in the regulation of vascular homeostasis.
atrium – (plural = atria) higher or acquiring chamber with the heart that pumps blood in the decrease chambers just before their contraction; the best atrium gets blood with the systemic circuit that flows into the ideal ventricle; the left atrium click here gets blood from the pulmonary circuit that flows to the still left ventricle.
anterior cardiac veins – vessels that parallel the compact cardiac arteries and drain the anterior area of the ideal ventricle; bypass the coronary sinus and drain specifically into the appropriate atrium.
arterial circle – (also, circle of Willis) anastomosis Situated at The bottom from the Mind that makes certain continual blood provide; formed from branches of The inner carotid and vertebral arteries; supplies blood to your Mind.
axillary vein – significant vein from the axillary region; drains the upper limb and turns into the subclavian vein.
basal cell – variety get more info of stem mobile located in the stratum basale and within the hair matrix that constantly undergoes mobile division, developing the keratinocytes of the epidermis.
