Unit 2-Histology Flashcards
Simple Cuboidal Epithelium
Location: Kidney tubules, small glands, ovary surface
Function: Secretion, absorption
Simple Squamous Epithelium
Location: Lungs (alveoli), blood vessels (endothelium), serous membranes
Function: Diffusion, filtration, secretion
Simple Columnar Epithelium
Location: Digestive tract (stomach, intestines), uterine tubes (ciliated)
Function: Absorption, secretion (mucus, enzymes)
Pseudostratified Columnar Epithelium
Location: Trachea, upper respiratory tract (ciliated)
Function: Secretion (mucus), movement of mucus via cilia
Stratified Squamous Epithelium
Location: Skin (keratinized), mouth, esophagus, vagina (non-keratinized)
Function: Protection against abrasion
Stratified Cuboidal Epithelium
Location: Sweat glands, mammary glands, salivary glands
Function: Protection, secretion
Stratified Columnar Epithelium
Location: Male urethra, some glandular ducts
Function: Protection, secretion
Transitional Epithelium
Location: Urinary bladder, ureters, part of urethra
Function: Stretching, distension of urinary organs
Areolar
Location: Under epithelial tissues, around organs and capillaries
Function: Cushioning, binding organs, immune defense
Adipose
Location: Under skin, around kidneys and eyeballs, abdomen, breasts
Function: Energy storage, insulation, protection
Reticular
Location: Lymph nodes, bone marrow, spleen
Function: Supportive framework for lymphatic organs
Dense Regular
Location: Tendons, ligaments
Function: Strong attachment, withstands pulling in one direction
Dense Irregular
Location: Dermis of skin, fibrous capsules of organs and joints
Function: Strength, withstands tension in multiple directions
Elastic
Elastic
Location: Walls of large arteries, bronchial tubes
Function: Allows stretching and recoil
Hyaline Cartilage
Location: Ends of long bones, nose, trachea, larynx, costal cartilage
Function: Support, cushioning, reduces friction
Elastic Cartilage
Location: External ear, epiglottis
Function: Flexibility, shape retention
Fibrocartilage
Location: Intervertebral discs, knee menisci, pubic symphysis
Function: Shock absorption, tensile strength
Bone (Osseous Tissue)
Location: Skeleton
Function: Support, protection, movement, mineral storage, blood formation
Blood
Location: Blood vessels
Function: Transport of gases, nutrients, waste, immune response
