The adult human skeleton commonly is made of 206 named bones. These bones might be grouped in two divisions: axial skeleton and appendicular skeleton.
acinus – cluster of glandular epithelial cells within the pancreas that secretes pancreatic secretion inside the pancreas.
coracoclavicular ligament – robust band of connective tissue that anchors the coracoid technique of the scapula to the lateral clavicle; offers vital oblique support for the acromioclavicular joint.
action possible – change in voltage of the mobile membrane in reaction to the stimulus that brings about transmission of an electrical sign; exclusive to neurons and muscle fibres.
Protection on the heart, lungs, along with other organs and buildings from the upper body generates a challenge rather unique from that in the central anxious process. These organs, the purpose of which consists of movement, enlargement, and contraction, must have a flexible and elastic protective masking. Such a covering is provided by the bony thoracic basket, or rib cage, which varieties the skeleton in the wall with the upper body, or thorax.
complement – enzymatic cascade of constitutive blood proteins which have antipathogen results, including the direct killing of germs.
bursa – connective tissue sac that contains lubricating fluid that stops friction between adjacent constructions, such as skin and bone, tendons and bone, or concerning muscles.
bicipital groove – intertubercular groove; narrow groove Positioned in between the bigger and lesser tubercles with the humerus.
alar cartilage – cartilage that supports the apex on the nose and can help form the nares; it's linked to the septal cartilage and connective tissue in the alae.
autonomic tone – contractile condition for the duration of resting cardiac more info action made by delicate sympathetic and parasympathetic stimulation.
bone marrow – tissue uncovered inside bones; the location of all blood cell differentiation and maturation of B lymphocytes.
bedsore – sore to the pores and skin that develops when locations with the body start out necrotising resulting from consistent force and not enough blood offer; also known as decubitis ulcers.
coronal suture – joint that unites the frontal bone to the proper and website still left parietal bones across the top rated from the skull.
absolute refractory interval – time during an motion interval when An additional action potential can not be produced since the voltage-gated Na+ channel is inactivated.
