Histology Flashcards
(26 cards)
Tissues
collection of particular cells, perform specific function
Simple Squamous Epithelium
single-layered, flat; for filtration and diffusion; located in blood vessel lining
Stratified Squamous Epithelium
Multi-layered, flat for protection; located in the mouth esophagus, and skin
Keratinized
more protective, waterproof, makes up epidermis of skin
Non-Keratinized
Less protective, lines mouth, esophagus, and vagina
Simple Cuboidal Epithelium
Single-layered, cube-shaped; for secretion and absorption; located in the ducts of glands and kidney tubules
Transitional Epithelium
Multi-layered, random shaped; stretches; located in bladder and ureters
Simple Columnar Epithelium
Single-layered, column-like structure; for absorption and secretion; located in intestinal lining
Pseudostratified Columnar Epithelium
multi-layered tall structure; for protection, secretion; located in respiratory lining
Areolar Loose Connective Tissue
deep within skin, between muscles, blood vessels, and nerves; cushions organs, provides support; located in the lungs
Adipose Loose Connective Tissue
deep to the skin, fat, provides paddings and cushions shocks, insulates; located in the buttocks, and breast; padding around eyes and kidneys
Dense Regular Connective Tissue
provides firm attachment, conducts pull of muscles, reduces friction between muscles; located in tendons and ligaments
Dense Irregular Connective Tissue
provides strength to resist forces from many directions; located in the dermis
Hyaline Cartilage
Provides stiff but still flexible support and reduces friction between bony surfaces; located between joints and tips of ribs and bones of the sternum
Fibrocartilage
resists compression, prevents bone-to-bone contact, and limits movement; located in pads within knee joints and intervertebral discs
Elastic Cartilage
provides support but tolerates distortion without damage and returns to original shape; located in auditory canal and epiglottis
Bone
supports and protects, serves as attachments of muscles, produces blood, stores minerals and fats
Cartilage
firm, semisolid extracellular matrix
Plasma
liquid ground substance
Chondrocytes
mature cartilage cells, helps make cartilage
Blood
fluid connective tissue with formed elements
Body membranes
formed from epithelial layer bound to underlying CT, line body cavities
Mucous Membrane
Mucosa, lines compartments that open to the external environment; digestive, respiratory, urinary, and reproductive tracts; performs absorptive, protective, and secretory functions
Serous Membrance
lines body cavities that do not open to the external environment, form parietal and visceral layers, this layer is in between; reduces friction between opposing surfaces
