Tissues Flashcards
*lining of blood vessels, heart (endothelium), lymph vessels, and alveoli of lungs; peritoneum
*single layer of flattened cells
*diffusion; filtration; secretion of lubricants
Simple Squamous
*ducts, secretory part of small glands; retina; kidney tubules; ovaries, testes; bronchioles
*single layer of squarish cells
*secretion; absorption
Simple Cuboidal
*ducts, glands; gut; small bronchi
*single layer of tall cells; free surface may have cilia or microvilli
*secretion; absorption; ciliated types move substances
simple columnar
*Trachea
*single layer of tall cells that look like they have differing heights, some not reaching the basal surface; nuclei seen at different levels
*secretion (mucus); propulsion of mucus by ciliary action
Pseudostratified Ciliated columnar
*lines the ureters, urinary bladder
*binucleated, “fluffy” cells that can change their geometry in response to tensional forces
*stretches readily and permits swelling/enlarging of urinary organ
Transitional Epithelium
*esophagus
*many stacked layers of squamous epithelium. Defined basal membrane
*living cells act as a protective barrier
Non-Keratinized Stratified Squamous Epithelium
There is something special about Non-keratinized Stratified Squamous Epithelium, what is it?
it must be kept moist
*skin
*protective barrier from abrasion and water loss
*thick layers of stratified squamous with waterproof keratin border
Keratinized Stratified Squamous Epithelium
*pituitary, thymus, pancreas
*secrete hormones directly into the bloodstream
Endocrine gland
*sweat, mammary, salivary, pancreas
*secrete a product onto a surface
exocrine gland
*under skin
*connect/serve as an anchor
*collagen and elastic fibers
Loose (areolar) Connective Tissue
*around organs
*insulation, energy, storage
*loose elastic and collagen fibers
Adipose Connective Tissue
*tendons and ligaments
*connects muscle to bone (tendon) and bone to bone (ligament
*densely packed collagen fibers
Dense Regular Connective tissue
*dermis of the skin
*connect epithelial tissue to the bone
*densely packed collagen fibers
Dense irregular Connective Tissue
*nose, fetal skeleton, ends of long bones
*movement
*thin collagen fibers
Hyaline cartilage connective tissue
*outer ear
*elasticity/flexibility
*mainly elastic fibers
Elastic Cartilage Connective Tissue
*disks of vertebrae, knee joint
*Movement
*strong collagen fibers
Fibrocartilage Connective Tissue
*ends of long bones (femur)
*Protection
*collagen and calcium salts
Spongy Bone Connective Tissue
*shafts of long bones (femur)
*Protection
*collagen and calcium salts
Compact Bones Connective Tissue
*blood vessels and heart
*transport gases, immunity, blood clotting proteins
*plasma
blood
*lymphatic tissue
*white blood cells congregate here (immunity)
*lymph
Lymph
*partner of bones (biceps, triceps, etc.)
*movement voluntary, striated
Skeletal Muscle
*heart
*pump blood involuntary, striated
cardiac muscle
*hollow organs, blood vessels
*blood flow in arteries is involuntary, lacks striations
Smooth Muscle
*axon (away from the cell body), dendrite (toward cell body), cell body, nucleus
parts of a neuron
sensory input from the PNS to the CNS
Sensory Neuron
*interprets/integrates data
*found ONLY in the CNS
Interneuron
carries messages from the CNS to the PNS (to an effector such as a gland or muscle)
Motor Neuron
provides nutrients for the neuron
astrocyte
engulfs debris
microglia
forms the myelin sheath in the CNS
Oligodendrocyte
Forms the myelin sheath in the PNS
Schwann Cell
