Histology and Integumentary Terms
| Question | Answer |
|---|---|
| Absorption | Movement of nutrients through epithelial tissue |
| Adipose Tissue | Fat storage |
| Aponeurosis | Flat sheet the attaches muscle to bone; similar to tendon |
| Areolar Connective Tissue | Basic supporting substance |
| Canaliculi | Extension of osteocytes for diffusion |
| Cancellous Bone | Spongey Bone |
| Collagen | Strong white fibrous protein |
| Compact Bone | Dense bone tissue |
| Connective Tissues | Large amount of matrix relative to cell |
| Cutaneous Membrane | Skin |
| Dendrite | Transmits impulse to nerve cell body |
| Endocrine Gland | Ductless; Produces hormones |
| Epithelial Tissues | Forms lining, coverings + gland |
| Erythocytes | Red blood cell |
| Exocrine Glands | Duct; Secretion into cavities or onto surfaces |
| Hemopoietic | Forms blood cells |
| Intercalated Disks | Interdigitation of cell membrane |
| Involuntary Muscles | In cardiac Muscle; Cardiac + Smooth |
| Lacunae | Houses and protects bones and cartillage |
| Lamellae | Calcified rings in dense bone |
| Leukocytes | White blood cells |
| Ligaments | Connects bone to bone |
| Mucous Membrane | Lines cavities that open to the exterior |
| Multiunit Smooth Muscles | Single cell, not a lone |
| Neuroglia | Nerve tissue that supports neurons |
| Neuron | Functional cell in nervous system |
| Osteoblasts | Bone forming cell |
| Osteoclasts | Cell that demineralizes bone |
| Osteocytes | Mature bone cell |
| Reticular Connective Tissue | Forms defensive web in bone marrow; Lymph nodes |
| Serous Membrane | Lines cavities and covers organs |
| Synapse | Terminus of an axon |
| Thrombocytes | Clotting cell |
| Albinism | White; Trait that results in absense of color |
| Arrector Pili | Multiunit smooth muscle that attaches to hair |
| Ceruminous Glands | Produces earwax |
| Dermis | Inner layer |
| Hairless Regions of Skin | Palm of hand and sole of feet; lips |
| Keratin | Waterproofing in skin |
| Melanin | Skin pigment produced by melanocyte |
| Sebaceous Gland | Oil (Sebum) producing blad |
| Sudoriferous Gland | Sweat gland |
| Temperature Regulation of Skin | Vasoconstriction (Cold) and Vasodilation (Warm) evaporation of sweat (Hot) |
| Ultraviolet Light (UV) | Stimulates skin to begin the process of producing Vitamin D |
| Vitamin D | Necessary to absorb calcium |
| Vitiligo | Autoimmune Disease that permanently prevents production of Melanin |
| Squamous Epithelial Tissues | Flat cells Simple - Air sacs of lung; Alveoli (Diffusion) Stratified - Protection, multilayer on skin (Keratin) and esophagus/vagina (no Keratin) |
| Columnar Epithelial Tissue (Non-ciliated Simple) | May have Villi, which increases absorptive area in small intestines Functions in absorption of nutrients and secretion of digestive enzymes Found in GI Tract |
| Columnar Epithelial Tissue (Ciliated Simple) | Moves material typically trapped in Mucous Found in Fallopian tubes and Spinal Cord |
| Columnar Epithelial Tissue (Pseudostratified) | Ciliated with only one layer that looks like many layers Found in the Trachea (Airway) |
| Cuboidal Epithelial Tissue | Simple - Found in kidneys, thyroid gland, ovaries; Associated with secretion and absorption (Filtration) Stratified - Found in sweat gland duct |
| Transitional Epithelial Tissue | Multiple layers that transition from flat to columnar/cuboidal Found in urinary bladder |
| Stratum Corneum | - Outer most layer of epidermis - Dead skin that are continuously sheds and replaced |
| Stratum Lucidum | - Resists exposure to friction - Found in palms of hands and soles of feet only |
| Stratum Granulosum | - Begins Keratin formation process - Cells begin to die here |
| Stratum Spinosum | Closely-fit cells for protection |
| Stratum Basale (Germinativum) | Deepest layer where cell division occured (Mitosis) |
