Chap 5: Connective Tissue Flashcards
All connective tissue derives from __
mesenchymal cells
Connective Tissue consists of __ and ___
- prominent ECM consisting of ground substance and 3 types of protein fibers
Connective tissue has 3 protein fibers which include:
collagen fibers, elastic fibers, reticular fibers
4 general types of connective tissue:
- connective tissue proper
- cartilage
- Bone
- Blood
Connective Tissue Proper is made up of
scattered cells called fibroblasts
What do Fibroblasts do?
secrete an extensive ECM filled with many types of protein fibers
Is connective Tissue Proper vascularized of avascularized
vascularized
- connective tissue proper
- most widely distributed class of tissue in body. contains fibroblasts]
- Cartilage
-flexible but resist tension, twisting and compression forces
(connective tissue Proper) loose (areolar)
- loose appearance
- has all collagen fiber in ground substances
- fibroblast nuclei
(connective tissue Proper) Reticular
- reticular fibers produced by reticular cells. (spleen and lmyph nodes)
(connective tissue Proper) adipose
- fat tissue made up of adipocytes, very little ECM , (around skin and lining organs
(connective tissue Proper) dense regular cartilaginous are ___ and are found __ (2)
- collagen fibers arranged in one direction, very strong structure (tendons and ligaments)
(connective tissue Proper) dense irregular cartilaginous are ___ and are found __ (3)
- collagen fibers arranged in many directions, also strong, (dermis , joints and skin)
(connective tissue Proper) dense elastic
- elastic fibers (lines large BV’s and certain ligaments
connective tissue functions
bindings and supporting tissue for all other tissues in body
Muscle Tissue Function
Adapted to contract
Cartilage cells consist of ___
Chondrocytes
Chondrocytes are in cavities called
Lacunae
The 3 types of Cartilage
Hyaline, Fibro Cartilage, Elastic
Is Cartilage vascular or avascular?
avascular
Hyaline Cartilage
- lacks protein fibers so gives a smooth glossy appearance
- provides frictionless surface for bones to articulate
Hyaline Cartilage is found ___ (4)
ears, nose, trachea, respiratory tract
Fibrocartilage
-a lot of fibers (collagen fibers
-
Fibrocartilage functions for
shock absorbance
Synovial joints which reduces friction are made up of
Articular Hyaline Cartilage
Elastic Cartilage is __ and found in ___
visible fibers that stretch and recoil; ear
Bone is ___
tissue containing osteocytes in ECM that consist of calcium and collagen fibers
Bones is arranged in layers called
Lamellae
Blood
consists of cells called erythrocytes and leukocyctes
and plasma in an ECM
Muscle Tissue is located in __ (3)
Skeletal muscle, walls of hollow organs and heart
The ECM of muscle tissue is known as
Endomysium
Tissues Layers from most superficial to deep are
Epithelial tissue –>Basement membrane–> connective tissue
Skeletal Muscle Tissue is shaped like __ and ___ (striated /unstriated) and ___ (Multi or Uninucleate)
long tubular; striated; multinucleate
Smooth Muscle Tissue is shaped like __ and ___ (striated /unstriated) and ___ (Multi/Uninucleate)
flat; and nonstriated; uninucleate
Cardiac Muscle Tissue is shaped like __ and ___ (striated /unstriated) and ___ (Multi/Uninucleate)
short/fat;striated; uninucleate
Smooth Muscle is found in __ (3)
Skin, eyes and glands
Simple cuboidal is found in __ (3)
glands, respiratory tract and kidneys
Elastic Fiber allows for
recoiling and stretching
Elastic Fiber is found in (3)
arteries, vertebral column and bronchial tubes
Reticular Fiber is found in (3)
Bone marrow , lymph nodes and small intestine
Pseudostratified lines
nasal cavity and respiratory tract
simple columnar lines __(3)
respiratory passage, genitourinary, and digestive tract
Stratified keratinized is found in places of ___ mechanical stress such as __ (
greater; outer layer of skin
stratified nonkeratinized is found in places of ___ mechanical stress such as
lesser; pharynx, anus and vagina
Keritanized has a superficial ___layer while nonkeritanized has ___ layer of cells
dead;live
Stratified Epithelium is found in __ (3)
Kidneys, sweat glands and bladder
Stratified Columnar is found in __ (4)
eyes, anus, throat, uterus, male urethra
