| Question | Answer |
| Gap Junction | allows communication between cells Eg. Epithelial Tissue |
| Adhesive Junction | for anchoring cells/cell adhesion Eg. Hemidesmosome, Adherens junction, desmosome |
| Tight Junction | barrier function ie. prevent the passage of molecules and ions through the space between plasma membranes of adjacent cells |
| Epithelial tissue | covers and protects surfaces, both outside and inside the body cell and matrix connections, nonvascular, capable of regeneration |
| Fuinctions of Epithelial tissue | Protecting underlying structures Acting as a barrier Permitting the passage of substances Secreting substances (glands) |
| Merocine Gland | mero = partial The gland releases its product and no part of the gland is lost or damaged |
| Apocrine Gland | apo = away from secretion by membrane budding (loss of cytoplasm) portion of the cell containing secretory products is pinched off |
| Holocrine Gland | holo = whole; complete entire cells are shed by the gland and become part of the secretion |
| Squamous | FLAT, hexagonal, scale-like Found in skin, inner cheek |
| Cuboidal | cube-like Found in kidney |
| Columnar | Rectangular, pillars, columns Found in the stomach |
| Simple (Layer) | Single layer |
| Stratified | Multiple layers |
| Pseudostratified | Appears to be multi-layer but the arrangement of cells are still simple (single) |
| Transitional (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. |
| Simple Squamous Epithelium | Function: 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 |
| Stratified Squamous Epithelium | Specialized in areas with high abrasion Can be keratinized or not Location: Mouth, vagina, tongue, anal canal, skin |
| Simple Columnar Epithelium | basal nuclei all in one line, elongated cell, single layer Location: stomach lining, gallbladder, collecting ducts of kidneys, intestine, uterine tubes |
| Stratified Cuboidal Epithelium | multiple layers of cube-like cells Location: Sweat glands, Salivary gland ducts Functions: Secretion, absorption, protection against infection |
| Stratified Columnar Epithelium | Function: protection, secretion Location: lanryx, mammary gland ducts |
| Pseudostratified Columnar Epithelium | Brush-like surface for cilia Function: protection & secretion |
| Simple Cuboidal | Characteristics: 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. |
| Adipose | Function: Energy storage, insulation, cushioning, contains lipids (fats) Location: deep in skin, buttocks, breasts |
| Loose Connective | Connects several tissues together Location: digestive tract, blood vessels, joints |
| Dense Connective | Connects bones/muscles Found in ligaments and tendons |
| Bone | Structural support, immune function (marrow) |
| Hyaline Cartilage | hyaline = having a glassy, translucent appearance provides flexible support reduces friction Commonly found in joints for support |
| Elastic Cartilage | Great flexibility Location: epiglottis, auricle of external ear |
| Fibrous Cartilage | Strong cartilage usually for high tension areas Location: pads within knee joint, intervertebral discs |
| Blood | Immune function (leukocytes) Nutrient and oxygen transport (erythrocytes) Clotting (thrombocytes) |
| Skeletal Muscle | Striated, multinucleated Voluntary Attached to bones, found in tongue |
| Smooth Muscle | Fusiform/spindle shaped Involuntary, unstriated Multiple functions: Lines vascular tissue, lines GI tract Found in visceral organs: stomach, small intestine |
| Cardiac Muscle | Found in the heart Striated; involuntary Intercalated disc: force muscle contraction |
| Nervous tissue | Function: Sensory input, Controls muscles and glands, Homeostasis (balance), Mental activity Location: Brain, spinal cord, nerves |
| Burns | |
| Tissue Damage and Repair |
