A Simple Key For human anatomy & physiology Unveiled

cholinergic method – neurotransmitter procedure of acetylcholine, which incorporates its receptors and the enzyme acetylcholinesterase.

steady conduction – sluggish propagation of an motion prospective along an unmyelinated axon owing to voltage-gated Na+ channels Found together your complete length of the mobile membrane.

carotid canal – zig-zag tunnel offering passage throughout the base from the cranium for The interior carotid artery into the brain; starts anteromedial to the styloid course of action and terminates in the middle cranial cavity, close to the posterior-lateral foundation on the sella turcica.

coronoid means of the mandible – flattened upward projection with the anterior margin in the mandibular ramus.

Replica is definitely the development of a different organism from guardian organisms. In humans, reproduction is carried out because of the male and woman reproductive systems. Because Loss of life will come to all advanced organisms, with out replica, the line of organisms would end.

DNA polymerase – enzyme that functions in introducing new nucleotides to your developing strand of DNA through DNA replication.

autonomic nervous method (ANS) – useful division with the anxious process which is responsible for homeostatic reflexes that coordinate Charge of cardiac and easy muscle mass, in addition to glandular tissue.

cornea – fibrous masking of the anterior area of the attention that is certainly clear making sure that light-weight can pass through it.

wide ligament – large ligament that supports the uterus by attaching laterally to both human anatomy & physiology sides on the uterus and pelvic wall.

anterior inferior iliac spine – tiny, bony projection Positioned to the anterior margin with the ilium, under the anterior superior iliac backbone.

cranial nerve – considered one of twelve nerves linked to the Mind that are accountable for sensory or motor features of The pinnacle and neck.

dorsal arch – (also, arcuate arch) formed within the anastomosis with the dorsalis pedis artery and medial and plantar arteries; branches supply the distal parts with the foot and digits.

Betz cells – output cells of the primary motor cortex that induce musculature to move by way of synapses on cranial and spinal motor neurons.

anterior cruciate ligament – intracapsular read more ligament in the knee; extends from anterior, top-quality floor of the tibia into the interior aspect of the lateral condyle of your femur; resists hyperextension of knee.
