angiotensin II – protein produced by the enzymatic motion of ACE on inactive angiotensin I; actively causes vasoconstriction and stimulates aldosterone release through the adrenal cortex.
corpus spongiosum – (plural = corpora cavernosa) column of erectile tissue from the penis that fills with blood through an erection and surrounds the penile urethra on the ventral percentage of the penis.
dense connective tissue – connective tissue correct which contains numerous fibres that present each elasticity and security.
hypertension – force exerted through the blood versus the wall of the vessel or heart chamber; is often explained While using the extra generic phrase hydrostatic tension.
Protection of your heart, lungs, together with other organs and structures while in the chest creates a dilemma to some degree diverse from that of the central anxious method. These organs, the perform of which entails motion, enlargement, and contraction, need to have a flexible and elastic protecting masking. Such a covering is provided by the bony thoracic basket, or rib cage, which varieties the skeleton of the wall with the chest, or thorax.
Determine the conditions anatomy and physiology, and give specific examples to show the interrelationship between anatomy and physiology

The central anxious procedure lies mostly within the axial skeleton, the brain currently being nicely guarded via the cranium and the spinal twine through the vertebral column, through the bony neural arches (the arches of bone that encircle the spinal twine) along with the intervening ligaments.
The connection in the ribs for the breastbone—the sternum—is in all circumstances a secondary a person, introduced about by the somewhat pliable rib (costal) cartilages. The modest joints between the ribs plus the vertebrae permit a gliding movement of your ribs around the vertebrae for the duration of respiration along with other activities. The motion is limited by the ligamentous attachments among ribs and vertebrae.
central anxious technique get more info (CNS) – anatomical division on the nervous program located in the cranial and vertebral cavities, specifically the brain and spinal cord.
cardiac plexus – paired advanced community of nerve fibres near the foundation of the heart that receive sympathetic and parasympathetic stimulations to manage HR.
blood-brain barrier (BBB) – physiological barrier among the circulatory process as well as the central anxious method that establishes a privileged blood source, limiting the circulation of substances in to the CNS.
basal mobile – type of website stem cell found in the stratum basale and in the hair matrix that frequently undergoes mobile division, manufacturing the keratinocytes in the epidermis.
