3rd degree burn (layer of skin affected) - epi and all of dermis/ nerve endings destroyed Compare and contrast an artery vs a vein. - artery - blood away from heart - oxygenated - thicker tunica media - smaller lumen vein - blood toward heart - deoxygenated - larger lumen - valves _________ means to provide nerve fibers to/from an organ or tissue. - Innervate 1st degree burn (layer of skin affected, appearance, healing time) - outer layer of epi/ red, swollen, pain/ 3-10 days to heal 2nd degree burn (layer of skin affected, appearance, healing time) - epi and papillary of derm/ blisters / 3-4 weeks 4th degree burn - entire integument, into muscle, bone tendon / amputation A ______ is where info is transferred between nerve cells. - synapse ABduction - Away from midlineADduction - toward the midline afferent neurons - sensory neurons alveoli - socket Anatomical Planes and Sections - Frontal/Coronal = Front & Back Saggital = any left or right vertical Transverse/Horizontal = across body Median/Midsaggital = middle Anterior - front Are epithelial tissues vascular or avascular? - avascular Axons direct information ________. - away from the cell body. Both conventional radiography and CT utilize x-rays. Which of the two result in superimposition of structures? - conventional radiology Compare merocrine and apocrine sweat gland locations and secretions. - Merocrine glands release water-like sweat for temp regulation; found on palms, soles of feet. Apocrine sweat contains fat/protein so smelly and needs hair follicles to secrete; found in axillary, genitals Compare T1 and T2 MRI's. - T1 = fat is whiteT2 = water is white Compare the location of periosteum and endosteum? - Periosteum is layer around the bone. Endosteum lines spicules and inner surfaces. Compare the role of cilia to that of microvilli. - Cilia keep substances moving while microvilli help trap them for absorption Complete the following about epithelium: Epithelia form the _______ layer of the body. Epithelia line.... Epithelia constitute most ______ tissue. - surface body cavities and hollow organs gland condyle - rounded, smooth articulating surface crest - narrow, ridge like Define and describe the type of tissue found in capillaries and endothelium. - Simple Squamous Epithelium. Endothelium is the inner layer of arteries and veins and the only layer that remains by the time the capillary bed is reached, therefore composed the capillary bed. Define articulation. - where 2 bones meet Define fissure - narrow, slit-like opening through a bone Dendrites direct information ______. - toward the cell body.Describe a cartilaginous joint and the 2 types. - united by hyaline cartilage and/or fibrocartilage 1. syndochondrosis (hyaline) 2. symphysis (fibrocartilage) Describe a fibrous joint and the 3 types - united by fibrous tissue gomphosis, suture, syndesmosis Describe anatomical position. - - Erect - Face/ Palms/ Feet forward - Upper limbs at side - Lower Limbs parallel Describe cilia - fingerlike, motile projections that help move along debris/other substances
