- 1Gap Junctionallows communication between cells
Eg. Epithelial Tissue - 2Adhesive Junctionfor anchoring cells/cell adhesion
Eg. Hemidesmosome, Adherens junction, desmosome - 3Tight Junctionbarrier function
ie. prevent the passage of molecules and ions through the space between plasma membranes of adjacent cells - 4Epithelial tissuecovers and protects surfaces, both outside and inside the body
cell and matrix connections, nonvascular, capable of regeneration - 5Fuinctions of Epithelial tissueProtecting underlying structures
Acting as a barrier
Permitting the passage of substances
Secreting substances (glands) - 6Merocine Glandmero = partial
The gland releases its product and no part of the gland is lost or damaged - 7Apocrine Glandapo = away from
secretion by membrane budding (loss of cytoplasm)
portion of the cell containing secretory products is pinched off
- 8Holocrine Glandholo = whole; complete
entire cells are shed by the gland and become part of the secretion
- 9SquamousFLAT, hexagonal, scale-like
Found in skin, inner cheek - 10Cuboidalcube-like
Found in kidney - 11ColumnarRectangular, pillars, columns
Found in the stomach - 12Simple (Layer)Single layer
- 13StratifiedMultiple layers
- 14PseudostratifiedAppears to be multi-layer but the
arrangement of cells are still simple (single) - 15Transitional (Layer)Cells of the basal layer are cuboidal, or cube-shaped, and columnar, or column-shaped, while the cells of the superficial layer vary in appearance depending on the degree of distension.
- 16Simple Squamous EpitheliumFunction: reduces friction, gaseous exchange, diffusion hotspots, filtration, secretion & absorption
Characteristics: flat, tightly packed, nucleus is spherical/disk shaped, single layer
Location: Alveoli, blood vessels, lymphatic vessels - 17Stratified Squamous EpitheliumSpecialized in areas with high abrasion
Can be keratinized or not
Location: Mouth, vagina, tongue, anal canal, skin - 18Simple Columnar Epitheliumbasal nuclei all in one line, elongated cell, single layer
Location: stomach lining, gallbladder, collecting ducts of kidneys, intestine, uterine tubes - 19Stratified Cuboidal Epitheliummultiple layers of cube-like cells
Location: Sweat glands, Salivary gland ducts
Functions: Secretion, absorption, protection against infection - 20Stratified Columnar EpitheliumFunction: protection, secretion
Location: lanryx, mammary gland ducts - 21Pseudostratified Columnar EpitheliumBrush-like surface for cilia
Function: protection & secretion - 22Simple CuboidalCharacteristics: Cells are cube shaped, usually as a lining for ducts thus the presence of lumen
Function:Secretion and absorption
Location: Kidney ducts, thyroid, other glands, etc. - 23AdiposeFunction: Energy storage, insulation, cushioning, contains lipids (fats)
Location: deep in skin, buttocks, breasts
- 24Loose ConnectiveConnects several tissues together
Location: digestive tract, blood vessels, joints
- 25Dense ConnectiveConnects bones/muscles
Found in ligaments and tendons
- 26BoneStructural support, immune function (marrow)
- 27Hyaline Cartilagehyaline = having a glassy, translucent appearance
provides flexible support
reduces friction
Commonly found in joints for support - 28Elastic CartilageGreat flexibility
Location: epiglottis, auricle of external ear - 29Fibrous CartilageStrong cartilage usually for high tension areas
Location: pads within knee joint, intervertebral discs - 30BloodImmune function (leukocytes)
Nutrient and oxygen transport (erythrocytes)
Clotting (thrombocytes)
- 31Skeletal MuscleStriated, multinucleated
Voluntary
Attached to bones, found in tongue
- 32Smooth MuscleFusiform/spindle shaped
Involuntary, unstriated
Multiple functions: Lines vascular tissue, lines GI tract
Found in visceral organs: stomach, small intestine - 33Cardiac MuscleFound in the heart
Striated; involuntary
Intercalated disc: force muscle contraction - 34Nervous tissueFunction:
Sensory input, Controls muscles and glands, Homeostasis (balance), Mental activity
Location:
Brain, spinal cord, nerves - 35Burns
- 36Tissue Damage and Repair
