Lab tissues & skin Flashcards
What are the 4 types of tissue ?
-Epithelial
-Muscular
-Connective
-Nervous
What are the different categories in Epithelial tissues ?
-simple squamous
-simple columnar
-simple cuboidal
-stratified squamous
-psudostratified columnar
Stratified squamous
Multilayered regenerates rapidly , fond in harsh environment in/on the body
Simple columnar
Single layer of tall column-like cells ,found in digestive tract / in testiness
Pseudostratified columnar
Squished and abnormally shaped columnar cells,usually found in upper respiratory tract , trachea
Simple squamous
Single layer of flat cells, found in capillaries, lungs
Simple cuboidal
Single layer of cube-shaped cells,found in kidneys and glands
Reproductive cells
Sperm and egg cells are haploid gamers
What are the categories of the CONNECTIVE TISSUE’S
- adipose
-Fibrous
-Bone
-Loose/Areolar
-Blood
-Cartilage
Adipose
Cells contain a large flat droplet , used for energy storage
Fibrous
Dense with collarino U.S. fibers, found in tendons and ligaments
Bone
Osteocytes ,osteoblast’s,and osteoclasts suspended in an extra cellular matrix of hard calcium
Loose/areolar
Binds epithelial and organs in place has loosely connected fibers
Blood
Made up of plasma, erythrocytes,leukocytes and platelets , Carrie’s nutrients and wastes
Cartilage
Chondrocytes secrete a rubbery matrix of collagen and chondroitin sulfate,found in joints
What are the categories of Muscle tissue ?
-skeletal muscle
-smooth muscle
-cardiac muscle
Skeletal muscle
Bundles of long ,un-branched,strained cells,responsible for voluntary movement !made up of sarcomeres
Cardiac muscle
Branched and striated, has intercalated disks to help transfer of electrical signals ,found only in the heart,responsible for contraction of the walls of the heart
Smooth muscle
Non-striated and spindle shaped , responsible for involuntary activity of things like the stomach and constriction/dilation of arteries
What are the different categories of nervous tissue
Neurons
Neurons
Receive and transmit signal throughout the body via the nervous system .can be found alone on neuron slides and also in the ventricular horns of spinal sections .
