anterior interventricular artery – (also, still left anterior descending artery or LAD) major department on the left coronary artery that follows the anterior interventricular sulcus.
cuticle – in hair, the outermost layer of keratinocytes originating from your hair matrix, as observed inside a cross-area with the hair bulb.
cortical response – subsequent fertilisation, the release of cortical granules within the oocyte’s plasma membrane to the zona pellucida developing a fertilisation membrane that prevents any even more attachment or penetration of sperm; part of the slow block to polyspermy.
anticodon – consecutive sequence of three nucleotides on the tRNA molecule that may be complementary to a certain codon on an mRNA molecule.
chordae tendineae – string-like extensions of hard connective tissue that extend from the flaps of your atrioventricular valves towards the papillary muscles.
cauda equina – bundle of spinal nerve roots that descend through the lower spinal wire down below the main lumbar vertebra and lie throughout the vertebral cavity; has the looks of the horse’s tail.
Bainbridge reflex – (also, named atrial reflex) autonomic reflex that responds to stretch receptors during the atria that mail impulses for the cardioaccelerator spot to enhance HR when venous circulation to the atria increases.
Anatomy and physiology both are connected with the composition and operating technique of a human body. All dwelling organisms on the planet are made up of cells, tissues, organs and organ methods.
Cells, for example, Use a mobile membrane (also often called the plasma membrane) that keeps the intracellular atmosphere—the fluids and organelles—independent within the extracellular setting. Blood vessels maintain blood inside of a shut circulatory system, and nerves and muscles are wrapped in connective tissue sheaths that independent them from encompassing structures.
dihydroxyvitamin D – Energetic kind of vitamin D necessary by the intestinal epithelial cells for that absorption of calcium.
acromion – flattened bony approach that extends laterally check here from the scapular spine to sort the bony tip with the shoulder.
artery – blood vessel that conducts blood away from the heart; could be a conducting or read more distributing vessel.
digital arteries – shaped through the superficial and deep palmar arches; provide blood into the digits.
basement membrane – in epithelial tissue, a skinny layer of fibrous content that anchors the epithelial tissue into the fundamental connective tissue; built up in the basal lamina and reticular lamina.
