Cards

Term
Histology
Definition
the study of tissue
Term
Kinds of Tissue (4)
Definition

Epithelial

Connective

Muscle

Nervous

Term
Epithelial Functions
Definition
  • forms the outer skin
  • lines body cavities
  • covers organs
  • lines organs
  • makes up glands
Term
Epithelial Tissue Characteristics
Definition
  • It always has a free surface and an attatched surface
  • no blood vessels
  • these cells reproduce very rapidly (the most)
  • no intercellular space
Term
Individual Types of Epithelial Tissue (6)
Definition
  • simple squamous epithelium
  • simple cuboidal epithelium
  • simple columnar epithelium
  • ciliated columnar epithelium
  • stratified squamous epithelium
  • glandular epithelium
Term
Simple Squamous Epithelium
Definition
  • one layer of flattened cells
  • found lining air sacs in the lungs and forming capillary walls
  • it is very thin so that diffusion can take place
Term
Simple Cuboidal Epithelium
Definition
  • one layer of cubed shape cells
  • found in the kidneys
  • they secrete or absorb substances
Term
Simple Columnar Epithelium
Definition
  • one layer of column-like cells (thicker)
  • secretes digestive juices
  • danger- could easily digest self
Term
Ciliated Columnar Epithelium
Definition
  • cilia beat and move mucase out
  • found in the respiratory passages and lining the female fallopian tubes
Term
Stratified Squamous Epithelium
Definition
  • layers of squamous epithelial cells
  • these cells are produced deep and move to the surface
  • found in the outer skin for protection, mouth, throat, anal canal, and vagina
Term
Glandular Epithelium
Definition
  • these cells manufacture and secretes substances
  • 2 types: exocrine glands (ducted glands) and endocrine glands (ductless glands)
Term
Connective Tissue Characteristics
Definition
  • have intercellular space and there are substances in the space
  • most common cell type is a fibroblast
  • have a blood supply this means it can bleed as well
Term
Fibroblast
Definition
  • makes white and yellow protein substances
  • white fibers are collagen
  • yellow fibers are elastin
Term
Collagen
Definition

found in bundles

is strong and flexible but cannot stretch

Term
Elastin
Definition
these fibers will stretch
Term
Matrix
Definition
the intercellular space
Term
Individual Types of Connective Tissue (6)
Definition
  1. Areolar Connective Tissue
  2. Adipose Connective Tissue
  3. Fibrous Connective Tissue
  4. Cartilage
  5. Bone
  6. Blood
Term
Areolar Connective Tissue
Definition
  • cell type --> fibroblast
  • cells are far apart with a jelly-like matrix
  • used to underline epithelial tissue and feed them by diffusion
  • if you damage your circulatory system it automatically damages the epithelial tissue
  • fluids can accumulate here causing swelling or edema
Term
Adipose Connective Tissue
Definition
  • fibroblasts store lipids inside of them
  • fat
  • this is found around muscles, kidneys, eyeballs, abdominal membranes, heart, and joints
  • uses of fat: energy storage, protection, insulation
  • some people believe if you over feed an infant you increase adipose cells causing obesity possibilities
Term
Fibrous Connective Tissue
Definition
  • contains a large amount of collagenous fibers closely packed 
  • this gives strength and flexibility but no stretching
  • this tissue binds body parts together
  • tendons-connects muscle to bone
  • ligaments- hold joints in place
  • white of the eye- gives eye the round shape
  • poor blood supply
Term
Cartilage
Definition
  • gristle
  • the cell type is chondrocyte
  • substance in the matrix is chondrin
  • lacks a blood supply, heals poorly
  • hyaline cartilage, elastic cartilage, fibrocartilage
Term
Hyaline Cartilage
Definition
  • looks white and sticky
  • found on the ends of bones, nose, and rings of the respiratory passages
Term
Elastic Cartilage
Definition
  • contains some yellow fibers
  • found in the outer eats and larynx
Term
Fibrocartilage
Definition
  • really tough
  • many white fibers
  • found in discs between vertebrae, in the knees, and between pubic bones in the pelvis
Term
Bone
Definition
  • the cell type is the osteocyte
  • the substance in the matrix is calcium salts
Term
Blood
Definition
  • the cell types are red blood cells, white blood cells, and platelets
  • the matrix is the plasma (or liquid part of the blood)
Term
Muscle Tissue Characteristic
Definition
these cells are contractile (they can shorten)
Term
Individual Muscle Tissues (3)
Definition
  1. striated muscle tissue
  2. smooth muscle tissue
  3. cardiac muscle tissue
Term
Striated Muscle Tissue
Definition

cells are long and thread-like and have lines going across

you can conciously shorten these cells

Term
Smooth Muscle Tissue
Definition

no striations so this contracts more slowly 

lines hollow organs (viscera)

Term
Cardiac Muscle Tissue
Definition

has striations but the cells are branching to form a bag which is the heart

these cells will contract without nerves stimulation

Term
Nervous Tissue
Definition
this tissue creates electricity and sends messages electrically to other parts
