The adult human skeleton commonly is made of 206 named bones. These bones may be grouped in two divisions: axial skeleton and appendicular skeleton.

arcuate line on the ilium – smooth ridge Positioned at the inferior margin of the iliac fossa; sorts the lateral portion of the pelvic brim.

bronchoconstriction – lower in the dimensions in the bronchiole as a consequence of contraction on the muscular wall.

typical iliac vein – considered one of a set of veins that flows to the inferior vena cava at the extent of L5; the remaining frequent iliac vein drains the sacral region; divides into external and inside iliac veins close to the inferior portion of the sacroiliac joint

Reproduction will be the development of a completely new organism from mum or dad organisms. In humans, reproduction is completed because of the male and woman reproductive programs. Since Dying will arrive at all intricate organisms, without the need of copy, the line of organisms would finish.

adrenal vein – drains the adrenal or suprarenal glands which might be straight away excellent on the kidneys; the proper adrenal vein enters the inferior vena cava right plus the still left adrenal vein enters the remaining renal vein.

choroid plexus – specialised construction containing ependymal cells that line blood capillaries and filter blood to create CSF while in the 4 ventricles with the brain.

bicipital groove – intertubercular groove; narrow groove Situated among the bigger and lesser tubercles in the humerus.

aortic arch – arc that connects the ascending aorta into the descending aorta; ends at the intervertebral disk involving the fourth and fifth thoracic vertebrae.

atrium check here – (plural = atria) upper or acquiring chamber in the heart that pumps blood in the decrease chambers just before their contraction; the correct atrium receives blood with the systemic circuit that flows into the ideal ventricle; the remaining atrium gets blood with the pulmonary circuit that flows into your left ventricle.

activation gate – Component of the voltage-gated Na+ channel that opens if the membrane voltage reaches threshold.

anterior spinal artery – blood vessel in the merged branches in the vertebral arteries that runs along the anterior surface area of your spinal wire.

ball-and-socket joint – synovial joint shaped amongst the spherical finish of one read more bone (the ball) that fits to the depression of the 2nd bone (the socket); identified at the hip and shoulder joints; functionally categorised to be a multiaxial joint.

anterior cruciate ligament – intracapsular ligament with the knee; extends from anterior, exceptional surface area with the tibia to the inner element of the lateral condyle of the femur; resists hyperextension of knee.
