Similar cells and extracellular matrix
Tissues
Study of tissues
Histology
Four types of tissues
Epithelial
connective
muscle
nervous
Give at least three characteristics of epithelial tissues
Found throughout the body cover surfaces abundant number of cells scanty intercellular substances attached to basement membrane avascular
Surface that is not attached to other cells
Free or apical surface
Surface that is attached to other cells
Lateral surface
Surface that is attached to the basement membrane
Basal surface
Give at least three functions of epithelial tissues
Protection protection barrier permitting the passage of substance secreting substances absorbing substances
Classification of epithelial tissue (number of cell layers)
Simple
stratified
pseudostratified
transitional
Classification of epithelial tissues (shape of the cell)
Squamous
cuboidal
columnar
Types of simple epithelium
Simple squamous
simple cuboidal
simple columnar
pseudostratified columnar
Single layer flat cells
responsible for:
the fusion and filtration
prevention of a board abrasion between organs
secretion and absorption
Simple squamous epithelium
Give at least three examples of simple squamous epithelium (location)
Linings of blood and emphatic vessels heart and Alveoli serous membrane filtration membranes of kidneys Air sacs of the lungs walls of capillaries
Single layer of cube like or tall as wide cell resting on the basement membrane
has microvilli or cillia
Simple cuboidal epithelium
Where does simple cuboidal epithelium usually found
Kidney tubules
glands and their ducs
surface of the ovaries
Made up of single layer of cells that are taller than they are wide
Has microvilli and Cillia
Simple columnar epithelium
This type of epithelium lines entirely the length of the digestive track from the stomach to the anus
Simple columnar epithelium
Type of simple epithelial tissue that has goblet cells
Simple columnar epithelium
Or pseudostratified columnar epithelium
Type of simple epithelial tissue that appears to be stratified but is actually a single layer of cells, all of which touch the basement membrane although not all reach the pics
Pseudostratified ciliated columnar epithelium
Where does pseudostratified columnar epithelium usually found
Nasal cavity
nasal sinuses
auditory tube’s
respiratory tract
Multiple layers of cells
its basal layer is cuboidal and its surface is flattened squamous cell
Stratified squamous epithelium
Types of stratified squamous epithelium
Keratinized and non keratinized
Which of the types of stratified squamous epithelium is moist
Non keratinized
Two rare types of epithelial
usually found in the ducts of large glands
Stratified cuboidal stratified columnar
A highly modified stratified type of epithelium who sells change in shape depending on whether the organ is distended or contracted
Transitional epithelium
What type of cell is present when transitional epithelium is stretched?
If not stretched?
Squamous cells
Cuboidal cells
This tissue is found all throughout the body
It has large amount of extra cellular substances such as protein fibers, ground substance and fluid
Connective tissue
Three types of protein fibers
Collagen reticular elastic
Give at least three functions of connective tissues
Protecting storing transporting connecting
What are the classifications of connective tissue’s
connective tissue proper (Loose connective tissue and dense connective tissues)
cartilages
bone
blood
Types of connective tissue proper
Loose or areolar
Adipose
Reticular
Dense regular/irregular
Types of dense connective tissue
Collagenous an elastic
Types of embryonic tissue base on number of layers
Endoderm
mesoderm
ectoderm
A type of connective tissue that is considered asUniversal packing material that binds organs together and keeps them in their proper position
fills spaces between organs
Loose or areolar connective tissue
Has ID adipocytes or fat cells
full of lipid
nucleus pushed to periphery
Adipose ct
A type of dense connective tissue you that resist stretching
example tendon and ligament
Dense collagenous connective tissue’s
A type of dense connective tissue that stretches and recoils
Dense elastic connective tissue
Types of cartilages
Hyaline fibrocartilage elastic
Most abundant type of cartilage that covers bone ends
Highland cartilage
A type of cartilage that resists pulling and tearing and withstand compression
It has intervertebral disc
Fibrocartilage
Type of connective tissue you that is predominantly composed of reticular fibers which are synthesized by reticular cells
Reticular connective tissue
What is the appearance of adipose tissue
Signet ring
A type of dense connective tissue that is made up of extracellular matrix that is packed with collagen use fibers that are compactly arrange in an orderly manner with fibroblast cells squeeze in between the collagenous bundles
Dense regular connective tissue
Type of dense connective tissue you that consist of densely packed collagenous fibers that are arranged in disorderly or irregular manner
Dense irregular connective tissue
This is a dense, firm but pliable, avascular type of connective tissue with an extracellular matrix consisting of collagenous an elastic fibers
Cartilage
A cartilage that is composed of a thread-like network of elastic fibers embedded within the matrix
Recoils
Elastic cartilage
It has osteocytes in the lacunae
Strong and rigid
Hardest type of connective tissue
Bone or osseous tissue
Two types of bone
Compact and spongy or cancellous
Unit of structure of bone tissue
Haversian system or osteon
What is present in the compact bone but absent in spongy which contains large spaces and in which the extracellular matrix is arrange as little beams called trabaculae
Osteons
Considered as a connective tissue you but it is consist of blood cells fibers in matrix
Liquid matrix
carry nutrients oxygen waste products etc.
Blood
Liquid portion of the blood
Plasma
Types of granulocytes
Neutrophil
Eosinophil
Basophil
Types of agranulocytes
Lymphocytes
Monocytes
A type of tissue specialize for contraction
Muscular tissue
A type of muscular tissue that is striated and voluntary
Long cylindrical units with multi nucleated appearance (periphery)
Skeletal muscle
Types of muscle tissue
Skeletal smooth and cardiac
Muscle of the heart
Striated and involuntary
Mono or bi nucleated
Cardiac muscle
What connects the cardiac muscles
Intercalated disk
A type of tissue that is non-striated and involuntary
They are made up of spindle or fusiform shape cells with a centrally located nucleus
Smooth muscle
A type of tissue that is found in the brain spinal cord and nerves
Nervous tissue
Parts of nervous tissue
Cell body
Axon
dendrite
Part of the nervous tissue that transmits impulses away from the cell body
Axon
Part of the nervous tissue that transmit impulses towards the cell body
Dendrites
Types of principal cell types found in nervous tissue
Neurons and neugrolia
