Tissue Flashcards
What are the 4 types of tissue?
Connective, epithelial, muscle, nervous.
Where does epithelial tissue cover?
Internal and external body surfaces.
What 3 things make up tissue?
Cells, intercellular material, fluid.
What is a simple squamous?
Epithelial - one thin layer of flat cells.
Where are simple squamous cells found?
In areas where diffusion occurs (blood vessels, alveoli and bowman’s capsule).
What are simple cuboidal cells?
Epithelial - one layer of cubed cells.
Where are simple cuboidal cells found?
Glands, kidney tubules.
What are simple columnar cells?
Epithelial - one layer of rectangle cells.
Where are simple columnar cells found?
Stomach and intestines.
What is stratified squamous?
Epithelial - layers of cells (two or more). It is tough and protective.
Where are stratified squamous found?
Areas with lots of friction - oesophagus, mouth, vagina.
What does stratified squamous do?
Put keratin (tough protein) into the cells (seen in epidermis of skin)
What is transitional epithelium?
Layer of thick cells with the ability to stretch.
Where would you find transitional epithelium cells?
Bladder.
What tissue are glands made up of?
Epithelial tissue
Are glands unicellular or multi cellular?
Both simple (uni) and compound (multi).
What are the 3 different shapes of glands?
Tubular, coiled and saccular.
Where are simple tubular cells found?
Small intestine.
Where are simple branched tubular glands found?
Stomach.
What are simple alveolar glands?
Sebaceous.
Where do you find simple alveolar glands?
Tail and anal glands.
What are simple coiled glands?
Sweat glands.
What is a compound alveolar gland?
Salivary gland.
What is a compound tubular glandand where is it found?
Duodenal gland in small intestine.
What does connective tissue do?
Binds and supports all other body tissues.
What is areola tissue?
Loose stretchy tissue.
What does the areola tissue do?
Forms layer between the skin and tissues beneath.
What does the areola tissue contain?
Blood vessels and fibres.
Does the areola tissue have more fibres or cells?
More cells.
What is apidose tissue?
A loose connective tissue that insultates the body.
What does the adipose tissue do?
Protects vulnerable organs.
What is fibrous tissue also known as?
Dense tissue.
What is the most common type of tissue?
Areola.
What tissue protects tendons, ligaments and the diaphragm?
Dense (fibrous) tissue.
What is yellow elastic tissue?
Dense tissue.
Where is yellow elastic tissue found?
Arteries and trachea.
What are the 2 types of bone tissue?
Compact and spongy.
Where is compact bone found?
Outer layer.
What is another word for spongy bone,
Cancellous.
Does cartialage contain blood vessels?
No.
What are the 3 types of cartilidge?
Hyaline, white fibrocartilage and elastic.
What is the most common cartilidge?
Hyaline.
What does fibrous cartilidge do?
Attaches tendons and ligaments to bone.
Where do you find fibrous cartilidge?
Scapula, menisci, intervertebral discs.
Where is elastic cartilidge found?
Pinna of the ear.
What is blood needed for?
Supplying nutrients and oxygen.
What is haemopoietic tissue?
Bone marrow.
What is haemopoietic tissue responsible for?
Producing blood cells.
What is lymphoid tissue responsible for?
Fighting infection and transporting fats.
What are the 3 types of muscle tissue?
Skeletal, smooth and cardiac.
What is skeletal tissue known as?
Striated or voluntary muscle.
Where is skeletal (striated/voluntary) muscle found?
Attached to the bones, bound together by connective tissue.
What is another word for smooth tissue?
Un-striated or involuntary muscle.
Where is smooth (un-striated/involuntary) found?
Throughout the body, bladder, lining blood vessels and respiratory tract.
Is there much connective tissue binding cells together is the cardiac muscle?
No
What 4 thing does each neuron consist of?
Cell body, nucleus, dendrons and axon.
What is a neuron?
A nerve cell.
What myelinated?
When the neuron is enclosed in a fatty sheath. Allowing electric impulse to move faster?
What is non-myelinated?
No fatty sheath, so impulses move slower.
What are afferent fibres?
Conduct information to the central nervous system.
