Chapter 5
What are the four classes of tissue found in the human body?
Epithelial, Connective, Muscular, Nervous
What type of burn would need a skin graph
3rd degree burn
How many bones are there in an adult ?
206 bones
Fill in the blanks
Slide 1
The epiphysis and the diaphysis
What tissue is the Epidermis made of ?
Stratified squamous keratinized epithelium
Where are these muscular tissues found in the body
-Skeletal Muscular Tissue
-Cardiac Muscular Tissue
-Smooth Muscular Tissue
Attached to bones
Heart
Visceral Organs
What are the 3 layers of the skin and type of tissue is it ?
Epidermis (epithelial tissue), Dermis (connective tissue), Hypodermis (connective tissue)
What is Appositional Growth?
Throughout a lifetime bones grow in diameter and
thickens
Fill in the blank
Slide 2
Cartilage - Fibrocartilage
Cartilage - Hyaline Cartilage
What is osteoporosis?
Its severe loss of bone density that is most common in postmenopausal women. Spongy bone is most affected and the bones are more prone to fractures
What are the two cell types and their function in nervous tissue ?
Neuron - transmits impulses
Neuroglia cells - supports neurons
Whats the difference between keratinized and non-keratinized, where can they be found on the body.
keratinized:contains the protein keratin, generates a dry, rough outer layer similar to that found on human skin
non-keratinized: lacks keratin, leaving a wet, porous surface such as the tongue
Describe the two types of bone ossification.
Intramembranous ossification
Replacement of fibrous connective tissue to form bone. Produces the flat bones of the skull and most of the clavicle
Endochondral ossification
Replacement of hyaline cartilage to form bone. Most bones develop this way.
Fill in the blanks from the top to the bottom
Slide 3
stratum basale
stratum spinosum
stratum granulosum
stratum lucidum
stratum corneum.
What are the steps is bone fracture repair? (4)
Formation of hematoma (blood clot) and granulation
tissue.
Formation of a soft callus.
Conversion to a hard callus.
Remodeling
What are the 3 things that make up connective tissues?
Specialized Cells
a. Fixed cells
b. Wandering cells
Extracellular Protein Fibers
Collagen, Reticular, Elastic
Ground Substance
Non-living fluid and substance
What are the stages of hair growth ?
Anagen Stage (Growing Phase), Catagen Stage (Degenerative Phase, Telogen Stage (Resting Phase)
Crystal of Hydroxyapatite allows the bone to be hard and withstand __________ forces.
Collagen fibers allow the bone to withstand ________ and give flexibility as a result.
Compressive
Tension
Fill in the blanks from top to bottom
What are the two layers in the middle blank
Slide 4
The epidermis
The dermis : the papillary layer and the reticular layer
The hypodermis
Draw stratified squamous, simple Cuboidal, and Pseudo stratified Columnar (Ciliated)
Slide 6
Look at the slides
Describe the two ways to repair tissue.
Regeneration is the replacement of
dead or damaged cells by the same
type of cells as before
Fibrosis is the replacement of
damaged tissue with scar tissue that
is composed mostly of fibroblasts and
collagen fibers.
The skin has five glands what are they ?
1. Merocrine sweat (sudiferous) glands
2. Apocrine sweat (sudiferous) glands
3. Sebaceous glands
4. Ceruminous glands
5. Mammary glands
Explain the the jobs for osteocytes, osteoblast, osteoclast, and osteogenic Cells.
Osteocyte: Mature bone cells, former osteoblasts. Guides the osteoblasts and osteoclasts what to do
Osteoblast: Bone forming cells and produce new bone matrix in a process
Osteoclast: Absorb and remove bone matrix. Break the bone to release calcium for the blood
osteogenic cells: Stem cells that produce daughter cells that give rise to most other bone cell types
Fill in the blank
Slide 5
Parietal bone Temporal bone
Occipital bone Frontal bone
Sphenoid bone Ethmoid bone
What glands are being shown
Slide 7
Merocrine Glands:Release product by exocytosis.
Apocrine Glands:Involve the loss of the product and some of the cytoplasm but the cell is not destroyed.
Holocrine Glands: Release product by bursting and the cell becomes the secretion.
