Tissue Concept Map
Epithelial
Simple
Squamos
Location:
Mouth, Anal Canal and Mouth
Function:
Allows passage of materials by diffusion and filtration in sites where protection is not important
3 Facts:
Single layer of flat cells in contact with the basement membrane
Cubiodal
Function:
Secretion and absorbtion
Location:
Kidney tubules, small galnds and ovary surface
3 Facts:
A single layered epithelium made up of cube like cells. The cells have large, spherical, and central nuclei
The cells either are active or passive depending on the location
Columnar
Location:
Anal canal, stomach, gallbladder and uterine tubes
Facts:
It is a uni-layered epithelium meaning that it has one layer to it
Simple columnar epithelium are split into two parts, Ciliated and non-ciliated
Ciliated moves mucus and is in the upper respiratory tract
Non-ciliated are found lining the gastrointestinal tract
Function:
Abosrbtion, secretion of mucus, enzymes and other substances
Stratified
Squamos
3 Facts:
Divided into two parts Keratinized and non-keratinized
Keratinized surfaces are protected by Keratin
Non-Keratinized surfaces do not have Keratin so they must be kept moist by bodily secretions
Location:
Esophagus and mouth
Function:
Protects underlying tissue in areas subject to abrasion
Columnar
Function:
Protection and secretion
3 Facts:
composed of column shaped cells arranged in multiple different layers
It is a very rare type of epithelial tissue
Location:
Small amounts in male urethra and in large glands
Cubiodal
Function:
Protection
Location:
Large ducts of sweat glands,mammary glands and salviary glands
Facts:
Made up of multiple layers of cube shaped cells
Connective
Fibrous
loose connective
Facts:
fibroblast cells are in the loose connective tissue and they secrete strong fibrous proteins
Location:
Between tissues and organs,
superficial fascia, and under epithelial
tissue
Function:
Most widespread connective
tissue; contains all cell and
fiber framework; makes
up volume
Dense
Irregulaur
Function:
Withstand tension and provide stuctural strength
Location:
Fibrous capsules of
organs and joints and dermis of skin
Regulaur
Location:
tendons, ligaments, ligaments between vertebrae,
along dorsal neck and vocal cords
Function:
Connection and protection
Reticular
Function:
Forms structural framework of organs
like lymph nodes, spleen, thymus, and bone marrow.
Location:
Lymph nodes, spleen and bone marrow
Elastic
Location:
Lungs; between vertebrae
of spinal column, ligaments
suporting penis and transitional
epithelia, blood vessel walls, permits expansion
and contractions of organs
Function:
Helps pump blood throughout
the body
Specialized
Bone
Function:
Provides support and protects
the organs
Location:
Bone
Facts:
filled with central canals which are surrounded by cells
red bone marrow is found in the spongy bone
Catilidge
Location:
Tips of ribs, sternum, larynx,
trachea, bronchi and part of
nasal septum
Function:
Provides stiff but somewhat flexible support and
reduces friction between bony surfaces
Facts:
contains a lot of elastic protein fibers which makes it very flexable
Three different types of cartilage, Hyline, elastic and Fibrocartilage
Blood
Facts:
contains proteins mixed with water to make gel
Location:
Blood
Function:
Transports oxygen through the body,
helps with immune system and protects
the body from infection and disease
Adipose
Location:
Under the skin, around kidneys
and eyes, in abdoman and in
breats
Function:
Insulates, protects and
supports organs.
Stores energy
Facts
loos connetive tissue made up of adopoctyes
Adipose tissue is more commonly known as body fat
Muscle
Smooth
3 facts:
Involuntary non striated muscle
Smooth muscle tissue are found within the walls of blood vessels also in the male and female reproductive tracts
Either the whole muscle contracts or the whole muscle relaxes. That is the case with this tissue and it is called being of the single unit variety.
Function:
Creates movement in hallow organs
Location:
Hallow organs
Cardiac
Function:
Movement and contraction
of the heart
3 facts:
The cardiac muscle is found on the walls and histological foundation of the heart
The cells that the Cardiac muscle are made up of only have three nuclei
The Cardiac muscle cells unlike most other tissues depend on blood to deliver blood and nutrients while getting rid of Carbon Dioxide
Location:
Heart
Skeletal
Location:
Bones
Function:
Produce skeletal movement, supports
soft tissue, stores nutrients etc.
3 facts:
Under control of the somatic nervous system
Skeletal muscles are attached to bones by collagen fibers called tendons
Every organelle of a muscle fiber is arranged to ensure form meets function
Nervous
Function:
Transmit impulses
3 Facts:
Made up of two part; the brain and the spinal cord
composed of neurons and neuroglia which transmit and receive impulses
made up of many different types of nerve cells which transmit potential action signals to the next cell
Location:
Central nervous system and peripheral nervous system
