Chapter 5 Flashcards
Anchored to connective tissue by nonliving layer called basement membrane
Epithelial tissue
Covers all body surfaces, inside and out
Epithelial tissue
Lack blood vessels, readily divides, and are tightly packed
Epithelial tissue
Functions in protection, secretion, absorption, excretion, and sensory reception
Epithelial tissue
Classified by the shape and number of layers of cells
Epithelial tissue
Goes out (leaves body)
Excretion
Produce in body; saliva and hormones

Supporting cells
Neuralgia cells
What are the three functions of the neuroglial cells
Support and bind nervous tissue
Carry on phagocytosis (engulf- wrapping around)
Connect neurons to blood vessels
Steps for reconstructing severely torn ligaments and tendons
Implant consists of carbon fibers coated with plastic.
Coated fibers sewn around torn ligaments and tendons to reinforce them.
Body’s own collagen fibers grow around them.
Within 2 weeks the plastic is absorbed and carbon fibers fracture.
Fibers now are completely covered in collagen
If one doesn’t have an immune system….
One cannot fight infections
Location of simple squamous
Gas exchange in lungs, body cavities, and lines blood and lymph vessels
Location of simple cuboidal
Covers ovaries and lines kidneys
Location of simple columnar
Lines uterus
Location of pseudo stratified columnar
Lines respiratory passage ways where cilia move the mucus and capture particles up and out
Location of stratified squamous
Covers skin, and lines mouth, and throat
Location of stratified cuboidal
Sweat, salivary glands, and pancreas
Location of stratified columnar
Male urethra and parts of pharynx
Location of transitional
Found in walls of various organs of urinary tract
Secretes into ducts
Exocrine
Secrete into the blood of tissue fluids
Endocrine
3 types of glandular
Merocrine glands
Apocrine glands
Holocrine glands
Releases a watery, protein, and rich fluid
Merocrine
Lose a portion of their cells during secretion
Apocrine
Entire cell disintegrates during secretion
Holocrine
Functions as connection, support, framework, fills spaces, stores fat, produces blood, protects against infection, and repairs damaged tissue
Connective tissue
Have abundance of matrix (intercellular material) of fibers and ground substance (fluid, gel, solid)
Connective tissue
Most have a good blood supply and can divide quite easily
Connective tissue
Difference between exocrine and endocrine glands
Exocrine secretes into glands and endocrine secretes blood into tissue fluids
Most common type, produce fibers
Fibroblasts
Phagocytes, scavenger and defense cell
Macrophage
Located near blood vessels, release heparin (prevents clotting) and histamine (cause inflation and allergies)
Mast cells
Protein collagen, great tensile strength (resists pulling force), ligaments and tendons
Collage nous
Protein elastin, very bone to bone, muscles-bones
Elastic
Where is elastic found
In the vocal cords
Very thin collagen fibers, support network
Reticular
Name the 3 cartilages, define, and locate them
Hyaline-most common, has very fine collagen fibers (nose, rings of respiratory passages, ends of many bones)
Elastic- more flexible, dense network of elastic fibers (ears and parts of larynx)
Fibrocartilage- very tough, has many collagen fibers (intervertebral discs, cushions the bones of knees and pelvis)
Bone cell
Osteocytes
Connective tissue is basically
Blood
