Tissue located in the kidney glomeruli, air sacs of the lungs, lining of the heart, blood vessels, and lymphatic vessels, lining of ventral body cavity (serosae)
Simple Squamous Epithelium
Located in kidney tubules, ducts and secretory portion of small glands, ovary surface
Simple cuboidal epithelium
Located in non ciliated type lines most of the digestive tract (Stomach & Rectum) , Gallbladder, and excretory ducts of some glands, ciliated variety lines small bronchi, uterine tubes, and some regions of the uterus
Simple columnar Epithelium
Located in the non ciliated type in male's sperm carrying ducts and ducts of large glands, cliliated variety lines the trachea, most of the upper respiratory tract
Pseudostratified columnar epithelium
Located in the non keratinized type forms the moist linings of the esophagus, mouth and vagina, keratinizied forms of the epidermis of the skin and dry membrane
stratified squamous epithelium
Lines the ureters, bladder and part of the urethra
transitional epithelium
Unicellular exocrine gland, produces mucin and mucin forms mucus. It is a cup like accumulation of mucin distends the top of the cel, making the cellslook like a glass with a stem.
Goblet Cells
Tiny, hair like projections on cell surface that move in wave like manner
Cilia
Connective tissue
Fibroblast
Erythrocytes, carries oxygen and nutrients, fluid tissue
Red blood cells
Leukocytes, neutrophils, eosinophils and other cell types that are concerned with tissue response to injury
White Blood cells
Clotting,
Platelets
Mature cell of a cartilage
Chondrocyte
Mature bone cells
Osteocytes
a formation of dense regular connective tissues which are cords that attach muscles to the bones
tendons
flat sheet like tendons that attach muscles to other muscles or to bones
aponeroses
bind bones together with the joints
ligaments
system of interconnecting canals in the microscopic structure of adult compact bone: unit of bone: also called osteons
Haversian Canal
extremely small tubular passage or channel
canaliculi
Description:Long, cylindrical, multi-nucleated cells, obvious striation
Location: Skeletal muscles attached to the bones or occasionally skin
Function: MovementL voluntary control
Skeletal muscle tissues
Description: Branching, striated, uninucleate cells that meet at special junctions (intercalated disc)
Location: The walls of the heart
Function: it contracts, propels blood into circulation, involuntary
Cardiac muscles
Description: Spindle-shaped cells with central nuclei, no striations, cells arranged closely to form sheath
Location: mostly in the wall of hallow organs (stomach)
Function: propels substance or objects along internal passageway (food, urine, baby), involuntary
Smooth muscles
Description: Neurons are branching cells, cells processes that may be quite long extend from the nucleus containing cell body, contributing to nervous tissue are non excitable supporting cells
Location: Brain, spinal cord and nerves
Nervous tissue
is 1st major skin region that is a keratinized stratified squamous epithelium
epidermis
is second major skin region that is strong, flexible connective tissue
Dermis
part of the dermis that is thing superficial made up of areolar connective tissue in which fine interlacing collagen and elastic fibers form loosely woven mat that is heavily invested with blood vessels. It patrols the area for bacteria that have breached the skin. Has papillae, projections which extends into epidermis. Friction ridges for finger prints
papillary layer
accounts for 80% of the thickness of the dermis and is irregularly arranged by dense fibrous connective tissue. many collagenous fibers. where suede leather comes from
reticular layer
Pressure ulcers usually occur in the skin overlying bony projections such as hip, heel, elbow or shoulder
decubitus ulcer
Are responsible for the sense of deep pressure and vibration located deep in the reticular layer
pacinian (lamellated) corpuscle
are responsible for the sense of light touch located in the dermal papillae. numerous in the nipples, external genitalia, fingertips and the soles of the feet
Meissner (tactile) corpuscle
deficiency of vitaimn d may lead to deformity of bonesm
rickets
young actively mitotic cell that forms the fibers of connective tissue. gel like ground substance
fibroblast
White fibers, extremely tough and tensile strength
Collagen
Elastic fibers, allows it to stretch and recoil
elastin
tissue which is found in tendons and ligaments. tissue is composed of large amounts of closely packed collagenous fibers.
Fibrous connective tissue
star shaped cells that arise from bone marrow and migrate to the epidermis. also called langerhans cell- ingest foreign substance. key activators of the immune system
dendritic cells
Markel cells function as a sensory receptor for touch
tactile cells
smooth muscle cells associated with hair follicles
arrector pili
each hair develops from epidermal cells at the base of a tube like depression called _________
hair follicle
sebaceous gland produce and oil secretion called
sebum
_______responds to emotional stress, have odors and considered scent glands. Most numerous in the armpits and groin. Also become active when a person is sexually stimulated
apocrine sweat gland
responds to elevated body temperature due to environmental heat or physical exercise. common on forehead, neck, back, where they produce profuse sweating on hot days and during physical exertion
eccrine sweat gland
Cells found just above the basement membrane which undergo rapid cell divisions. Also called the stratum basale. Basal cell carcinoma originates here.
Stratum Germinativum
is a middle portion of the epidermis several cells thick. The name derives from the appearance of these cells after they are fixed and processed for sectioning. The cells shrink but remain attached to each other by desmosomes giving the cells a "spiny appearance".
Stratum Spinosum
is a layer just above the spinosum in which large amounts of keratohyalin is being synthesized. Granules of this basophilic protein can be seen in stained sections.
Stratum granusolum
