Lab 3 Flashcards
What is the location, function, characteristics, and structures of simple squamous epithelium?
Location: Endothelium: segments of kidney tubules, lines lymphatic and cardiovascular vessels, lung alveoli, capillary lining. Mesothelium: Lining body cavities and internal organs
Function: Endothelium: Facilitate rapid passage of chemical compounds Mesothelium: Smooth & protective surface, secrete lubrication fluids
Characteristics: Cells and their nuclei are flat, horizontal, and elliptical
Structures: Basement membrane, Lumen, single layer
What is the location, function, characteristics, and structures of simple cuboidal epithelium?
Location: kidney tubule lining and ducts of glands
Function: Secretion & absorption of molecules
Characteristics: Cells are box-like and nuclei are round and in the center of the cell.
Structures: Basement membrane, lumen, single layer boxy cells
What is the location, function, characteristics, and structures of simple columnar epithelium?
Location: Lining of some sections of the digestive system and parts of female reproductive tract. With Cilia: Fallopian tube lining and parts of respiratory system
Function: Secretion and absorption of molecules With Cilia: remove particulate matter
Characteristics: Cells are tall and column-like and nuclei are elongated and located at the basal side
Structures: Basement membrane, lumen, single layer, goblet cell, microvilli
What is the location, function, characteristics, and structures of pseudostratified columnar epithelium?
Location: Respiratory tract
Function: Cilia: Remove particulate matter Goblet cells: secretion
Characteristics: Cells are irregularly shaped and differently sized columnar cells. Nuclei are at opposite ends of neighboring cells
Structures: Basement membrane, lumen, single layer, goblet cells cilia
What is the location, function, characteristics, and structures of stratified squamous epithelium?
Location: skin, lining of mouth cavity
Function: Protects against physical and chemical wear and tear
Characteristics: Layers of squamous cells, may have columnar/cuboidal cells toward basal side
Structures: Basement membrane, lumen, single layer, basal/ apical layers of cells
What is the location, function, characteristics, and structures of areolar connective tissue?
Location: Spaced between muscle fibers, surround blood lymph vessels, support organs in abdominal cavity,
Function: Support
Characteristics: All cell types (fibroblasts, fibrocytes, adipocytes, mesenchymal, macrophage, mast cells) and fibers (collagen, elastic, reticular) in random weblike formation
Structures: Collagen fibers, elastic fibers, fibroblasts
What is the location, function, characteristics, and structures of adipose tissue?
Location:
Function: Lipid molecule storage, insulation from cold temperatures, and protection from mechanical injuries.
Characteristics:
Structures: Collagen fibers, adipocytes
What is the location, function, characteristics, and structures of dense regular connective tissue?
Location: ligaments, tendons
Function: Strength without stretching
Characteristics: Greater resistance to stretching, parallel fibers
Structures: Collagen fibers, fibroblast
From superficial to deep what are the layers of the epidermis?
stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, stratum basale.
From superficial to deep what are the layers of the Dermis?
The papillary layer includes the dermal papilla, Meissner’s or tactile corpuscle (sensory structure), and blood vessels.
The reticular layer includes arrector pili muscle, blood vessels, hair bulbs, sebaceous glands, and sudoriferous glands.
What are the components of the hypodermis?
The hypodermis, or subcutaneous layer, is adipose tissue, Pacinian/lamellar corpuscle, and blood vessels.
