lecture notes
Terms
-
Adipose Connective tissue (FAT-think LONG TERM __)
- little extracellular matrix (fat cells) function in packing material, thermal insulator, energy storage located around kidneys and mammary glands
-
4 types of tissue and what they do
- epithelia-covers & lines surfaces, Connective-bind & support body parts, Muscle-movement, and nervous-detects changes & transmit info
-
Dense Collagenous Connective tissue
think ligament
- matrix composed of collagn fibers (inthe dermis) Function: ability to withstand pulling forces. located in tendons ligaments found in the dermis of skin.
-
what divides rapidly on the basement membrane?
and ____is not in contact with other cells
-
basile cells
free surface
-
where are simple columnar ET found?
think column think long lines.
- the nuclei are located near the base of the cells. forms the lining of the stomach and intestine/ sensroy reception nose, ears tast.
-
where is simple cuboidal ET found?
DKG
-
glands and kidney tubules as well as in ducts and glands.
-
which body cavity is lined with serous membrane? and are they open or closed?
what is serous fulid?
-
Pleural (lungs), peritoneum (addominal cavity & covers organs) and pericardium which surrounds the heart lines closed cavities
a lubricant
- bone
-
many osteocytes it provides strength and support and protects located in all bones of the body ex cancellous and compact bone
-
characteristics of CT
-
Few cells, non living matrix, found in all body parts, BINDS body components together VASCULAR(blood vessels) and FIBROBLASTS -secretes fiber.
-
characteristics of epithelial tissue, how are they arranged, functions,
-
tightly packed cells, arranged in layers. free surface & basement membrane below. To protect absorb, sensation, secretion. High rate of cell division healing. rely on diffusio-getting rid of bad stuff
-
classifications of connective tissue 6 types (2 branch off into another group)
-
Loose or areolar &n
- classifications of epithelial tissue (layers) and the 4 shapes
- simple (one layer), stratified(>1layer) Shapes: Squamous, cuboidal, columnar (tall & thin) and transitional which has no particular shape
-
connective tissue blood
- blood cells& fluid matrix. It transpors oxygen carbon dioxide hormones nutrients and waste. located within blood vessels white blood cells frequently leave the blood vessels. more red
- Connective tissue has how many cells scattered along what kind of matrix?
- fewer cells scattered along NON living matric that is solid or semi solid. CT is the mot abundant by weight.
- diffusion occurs easily or harder with simple squamous et?
-
diffusion occurs easily
-
does Epithelial tissue have intercellular spaces?
- NO and a small amount of substance. HAS BASEMENT MEMBRANE- which provides support for the epithelium and also binds it to neightboring structurs.
- fibrocartilage
- similar to hyaline, fibers more numerous. function flexible and located at disks
-
Functions of CT
- enclosing and seperatin, connecting tissue to one another, supporting and moving, storing, cushioning, transporting and protecting cells.
-
hyaline cartilage
-
function: allows growth of long bones, located in respiratory system
-
integumentary list some general info on it
- Organ System, Dermatolog (study of skin)It is the largest organ by weight, includes 4 primary tissue types, and aids in excretion of waste products
-
list the four types of membrans and what tissue i can find them in
-
ET and CT have Cutaneous (skin) Mucous (open) and Serous (close) Connective tissue has Synovial added on to its list
-
list the integumentary structure:
- cutaneous membrane (dry) it has 2 layers Epiderms and the Dermis (with deeper hypodermis) and accessory structures like hair folicule, shaft and sweat glands.
-
Loose Connective tissue
-
a fine network of fibers. mostly collagen fibroblasts located in here. Function is loose packing, support and nourish. Located thoughout the body underlying tissue skin dermis
-
name the 2 groups epithelial is divided into, and what are the names
-
simple: one layer and stratified: multiple layers. Simple can be subdived according to the shape and functoin of its cells.
-
name the connective tissue membrane
-
Synovial it lines freely moveable joint cavities (bursae, tendon sheaths) it lubricates and provides nutrients
-
name the structure, function and location of simple columnar epithelium tissue
- single tall layer, function:movement of particles out of the lungs by cilitated cells. Goblet cells secrete musus. it protects absorbs and secretes and lines digestive track and uterus
- name the structure, function and location of simple cuboidal et
- structure: single layer, some have microvilli or cillia. Function: active transport & facilitated diffusion in secretion & absobtion by cells. Located in kidney tubules, glands and their ducts.
- name the structure, function and location of simple squamous epithelium
-
single layer-falt, diffusion, filtration, some secretion and protection, and located lining of blood vessels, heart, lungs, serous membrane body cavities.
- pseudostratified columnar et (struction:LAYERS, function and where we find it in the body
- single layer of cells. function: synthesizes & secretes mucus onto free surface & moves. Location: lining the nasal cavity sinuses, trachea and lungs
- stratified cuboidal epithelium
- more than one layer, found in sweat glands and functions in absorption and secretion
-
stratified Squamous ET structure function location
- several layers that are cuboidal in the basal laye and flatter toward the surface . It protects against abrasion, barrier against infection and reduces loss of water from the body. dound in mouth throat skin esophagus.
- the basement membrane can function as a what in epithelial cells?
-
can function as a filter & barrier for movement
-
transitional et is a special type of stratifies ET that can be greatly (what amanda loves to do)
-
STRETCHED itlines the urinary bladder
function is accomidating fluxuation in fluid volume
- transitional has how many layes and what shape? where is it located?
- many layers and the cell shape changes-streche. location: lines the urinary bladder.
-
what are fibroblasts? and what are Osteocytes?
-
are cells that form fibers abd ground substances in the matrix of C Tissue. Osteocytes maintain bone
- what are the two folding layers of serous fulid?
- 1) parietal-lines wall of ventral body cavity lungs 2) Visceral- covers organs
- what tissue is on the top layer of skin
-
epithelial stratified squamous, superficial is dermis
-
where are squamous cells located?
-
they line body cavities like the mouth, blood vessels, heart and lungs and make up hte outer layer of the skin.
