Flashcards in Histology Deck (62):
What are the 4 primary tissues?
Epithelial, connective, muscle and nerve tissue.
What type of tissue is used for covering or lining?
Define epithelial tissue.
Tissue that is used for covering and line; secreting tissue
Define connective tissue.
Tissue that bind things together; fills in space.
What type of tissue binds things together, or fills in space.
What tissue shortens to produce movement?
Define muscle tissue.
Tissue that shortens to product movement.
Which tissue conducts impulses?
Define nerve tissue
Tissue that conducts impulses
The lung tissue that gases pass through to enter the blood is composed of what?
Simple squamous epithelial tissue
Which of the following is composed of dense regular connective tissue.
The achellis tendon, because we want it to be strong
Which of the following is true about the serous membrane
The serous membrane that cover the lung is called pleura.
Where does mitosis happen most rapidly?
Which tissues do not undergo mitosis typically.
Muscle and nervous
In which tissue does the rate of mitosis vary?
What are the functions of epithelial tissue?( not all do all function it varies)
Synthesizes structures, secretes substances, absorbed substances, and --------- underlying structures.
List 4 characteristics of epithelial tissue.
Cells are packed tightly, one apical surface and one basal surface attached to the basement membrane, cells reproduce rapidly, and not vascular.
How can you classify epithelial tissue.
By number of layers ( simple, stratified, suedostratified)
By shape ( squamous, cuboidal, columnar)
By whether it is ciliated or not
Define transitional epithelial.
Apical cells change shape, lines organs thy stretch
How would you classify the function of epithelial tissue?
Covering, lining and glandular
What is glandular epithelial tissue composed of?
Composes parenchyma of glands (the functional component)
Also secretes compounds
Functional component of glands
The matrix or supporting tissue of an organ
What are the two classifications of glands
Secrete hormones directly into the body or body fluid
For the most part the are simple cuboidal
Excrete to an external surface or into a cavity that leads to the outside of the body
Examples of exocrine glands
Examples of exocrine glands that secrete onto internal surfaces
Characteristic of connective tissue
Separated by a matrix (consisting of fibres and ground substance between cells
Structures vary greatly
Fibres and ground substance; makes up the matrix
Produce histamine (cause an inflammatory reaction)
What is ground substance composed of
Hyaluronic acid (the glue)
Chondroitin sulfate, dermatan sulfate, keratin sulfate
What 5 main cells are found in connective tissue
What is hyaluronic acid?
A viscous substance that facilitates movement of phagocytes and has protective qualities.
Broken down by hyaluronaise
Which of the three main substances in ground substance supports cartilage, bone, skin, blood vessels and atrial valves.
1. Hyaluronic acid
3. Chondroitin sulfate, dermatan sulfate, keratan sulfate
3. Dermatan sulfate, Chondroitin sulfate, keratan sulfate
Fibronectin (adhesive protein)
Links components of ground substance together
What is the general function of connective tissue
Name 3 types of fibres
Elastic (made of elastin; stretch)
Collagen (strong, resistant fibres with some flexion)
The matrix supporting tissue of organs
Name 5 types of mature connective tissue
Loose connective tissue
Dense connective tissue
Name three types of loose connective tissue
Name three types of dense connective tissue
Name three types if cartilage
Red blood cells
White blood cell
Pliable later of epithelial or/and connective tissue
The principal epithelial membranes are...
Two main types of membrane are...
Mucous membrane function.
- secretion of mucus
-found lining open cavities
(Type of epithelial membrane)
Name the two layer in Serous membranes
Pariatal- lines closed cavities
Visceral- covers outer surface of organs
what is the function of serous fluid
Reduce friction on serous membranes
What are the three types of serous membrane and where are they found.
Peritoneum (abdominal cavity)
Where is the visceral pleura
Covers the outer surface of the lungs
Where is the parietal pleura
Lining the thoracic cavity distal to the visceral pleura
What is found between the visceral layer and parietal layer of a serous membrane?
Line cavities of freely moving joints
