Q-1 Flashcards
Squamous Epithelium
Location- Air sacs of lungs, lining blood vessels / flat
Function- Allow passage of lquids and gases
Epithelial tissue- 3 types
Columnar Epithelium
Location- Digestive tract lining/ long and slender
Function- Secretion, Absorbtion, Protection
Epithelial tissue- 3 types
Cuboidal Epithelium
Location- Gland ducts/ square
Function- Secretion
Epithelial tissue- 3 types
Areolar (Loose Connective)
Within muscle tissue, skin, and blood vessels/fibroblast cells (synthesize fibers and matrix) in a semifluid matrix, delicate, very flexible.
Function- Support
(Connective tissue-6 types)
Dense Connective
Tendons and ligaments/fibers, stress resistant, regularly or irregularly arranged
Function- Support
(Connective tissue-6 types)
Adipose
Aggregations throughout the body/ thin cytoplasm around fat-storage vacuole(s)
Function- Food storage, heat production organ protection
(Connective tissue-6 types)
Blood
Within heart and blood vessels/cells in a fluid matrix
Function- CO2 and O2 transport, immune functions, clotting
Connective tissue-6 types
Cartilage
ends of bone, respiratory track, nose, ear/abundant fibers, chondrocytes (secrete matrix) in lacunae (matrix cavities)
Function- Stress absorption, support, bone growth
(Connective tissue-6 types)
Bone
Skeletal structure/ cells in lacunae arranged in concentric circles surrounding haversian canals (vessel portals). Lacunae are interconnected by canaliculi (perforations in matrix)
Function- Support, protection, calcium reserve
Marrow produces blood cells
(Connective tissue-6 types)
4 components of blood
Erythrocytes, Leukocytes, Platelets, and Plasma
Skeletal
attached to skeleton/cylindrical. multinucleate, striated
Function- Voluntary movement
Muscle Tissue- 3 Types
Cardiac
heart/cylindrical, one or two nuclei, striated, intercalated disks (junctional complexes)
Function- Pump blood through body
(Muscle Tissue- 3 Types)
Smooth
Digestive track and blood vessels/ elongated, one nucleus, non-striated
Function- Involuntary movement of blood and food
(Muscle Tissue- 3 Types)
Neurons
brain, spine, network throughout body/cell body, myelinated axon, branched dendrites
Function- Conduct impulses
(Nervous Tissue- 2 types)
Glial
Surrounding neurons/ gel-like cell body with processes (projections of the cell body)
Function- Support and nourish neurons, provide myelin
(Nervous Tissue- 2 types)
