exam 2 Flashcards
identify the location, funtion and shaped,Simple Cuboidal Epithelium
Identification: A single layer of flattened, elongated cells, arranged around a larger empty space
Location: Kidney tubules.
Function: Absorption and secretion.
Features to know: Round nuclei.
identify the location, funtion and shaped, Simple Squamous
Location: Forming the walls of the alveoli of the lungs, lining blood vessels, forming the walls of capillaries, serous membranes.
Function: Expedites diffusion and filtration.
Features to know: Flattened, oval-shaped nuclei.
Identification: A single layer of cubelike cells with large round nuclei, usually arranged in a circle
identify the location, funtion and shaped, Simple Columnar
Location: Lining the small and large intestines.
Function: Absorption and secretion.
Features to know: Goblet cells (1), nuclei (2), microvilli (3).
Identification: A single layer of tall, column-like cells with a single, neat row of oval-shaped nuclei, usually toward the base of the cell.
identify the location, funtion and shaped, Pseudostratified Columnar
Location: Lining the trachea and uterine tubes.
Function: Secretion and movement of mucus.
Features to know: Goblet cells (1), nuclei (2), cilia (3).
Identification: A single layer of cells of differing heights.
identify the location, funtion and shaped, Non-keratinized Stratified Squamous
Location: Lining mouth, esophagus, and vagina.
Function: Protection from abrasion and infection.
Features to know: Nuclei.
Identification: Many layers of cells.
identify the location, funtion and shaped,Transitional Epithelium
Location: Ureters, urinary bladder.
Function: Elasticity, stretch and recoil.
Features to know: Nuclei.
Identification: Many layers of cells with varying and irregular shapes. Causes an irregularly shaped inner region
identify the location, funtion and shaped,Areolar Connective Tissue
Location: Surrounding most organs just deep to the epithelium.
Function: Wraps and cushions organs, holds fluids and defensive cells
Features to know: Collagen fibers (1), Elastic fibers (2), Fibroblasts (3).
Identification: Loose arrangement of thick collagen and thin elastic and reticular fibers that crisscross randomly
identify the location, funtion and shaped,White) Adipose Connective Tissue
Location: Under skin, around eyes and kidneys, in breasts and buttocks.
Function: Energy storage, cushioning, insulation.
Identification: Greatly enlarged cells (adipocytes), nearly the entire volume of which is filled with a fat vacuole
identify the location, funtion and shaped,Reticular Connective Tissue
Location: Spleen, bone marrow, lymph nodes.
Function: Forms a scaffolding to support loose tissue cells.
Features to know: Reticular fibers (1), Lymphoblast (2)
Identification: Dark-staining reticular fibers, many nuclei of lymphoblasts and other cells.
identify the location, funtion and shaped, Dense Regular Connective Tissue
Location: Ligaments and tendons.
Function: Attaches bone to bone or bone to muscle, resisting tensile forces on a single direction.
Features to know: Fibroblast nuclei
Identification: Densely packed parallel fibers with fibroblasts
identify the location, funtion and shaped,Dense Irregular Connective Tissue
Location: Dermis of skin.
Function: Provides resistance against tensile forces in many directions.
Features to know: Fibroblasts
Identification: Irregular clumps of collagen fibers separated by space, with an overall blotchy appearance.
identify the location, funtion and shaped,Elastic Connective Tissue
Location: Walls of blood vessels, but more abundant in arteries than veins.
Function: Elasticity.
Features to know: Fibroblasts
Identification: Densely packed collagen fibers with dark wavy elastic fibers
identify the location, funtion and shaped, Hyaline cartilage
Identification: Smooth, glassy appearance with distinctive lacunae, most occupied by chondrocytes. Lacunae often paired.
Location: Nose, larynx, trachea, costal cartilage, covering ends of long bones.
Function: Structural support, cushions joints.
identify the location, funtion and shaped, Elastic cartilage
Identification: Distinctive large, often paired lacunae. Dark elastic fibers.
Location: Earlobe and epiglottis.
Function: Flexibility
identify the location, funtion and shaped, Fibrocartilage
Identification: Nearly parallel, wavy collagen fibers with distinctive chondrocytes in lacunae.
Location: Intervertebral disks, pubic symphysis, menisci of knee.
Function: Resist compressive forces.
