TISSUES AND ORGANS Flashcards
(97 cards)
These are aggregates of cells of a particular type or type.
TISSUES
What are the tips for studying tissues and recognizing them?
1) Note the cell details
A. Shape of the cell - square, rectangular, flat, spindle-shaped
B. Location of the nucleus - near the base of the cell, centrally located, near the top of the cell
C. Shape of the nucleus - round, oval elongated
D. Are the cells ciliated?
2) Tissue details:
A. Is the cell multinucleated?
B. Are the cells closely packed or loosely arranged?
C. What are the parts of the tissues? Identify them.
3) Drawings
What are the FIVE (5) GENERAL TISSUE TYPES?
1) EPITHELIAL TISSUE
2) CONNECTIVE OR SUPPORTIVE TISSUES
3) BLOOD OR VASCULAR TISSUE
4) MUSCULAR OR CONTRACTILE TISSUE
5) NERVOUS OR CONDUCTILE TISSUE
What are the SEVEN (7) TYPES OF EPITHELIAL TISSUES?
1) SQUAMOUS
2) COLUMNAR
3) CUBOIDAL
4) CILIATED
5) STRATIFIED EPITHELIUM
6) UNICELLULAR GLANDS
7) MULTICELLULAR GLANDS
WHAT ARE THE THREE (3) TYPES OF CONNECTIVE OR SUPPORTIVE TISSUES?
1) FIBROUS TISSUE
2) CARTILAGE
3) BONE
WHAT ARE THE THREE (3) TPES OF MUSCULAR OR CONTRACTILE TISSUE?
1) VISCERAL MUSCLE (SMOOTH, INVOLUNTARY)
2) CARTILAGE MUSCLE (STRIATED, INVOLUNTARY)
3) SKELETAL MUSCLE (STRIATED, VOLUNTARY)
A line drawing showing the sequence of the various tissue layers and the general contour in which they appear in the organ.
TISSUE MAP
What tissue part is this:
- The enclosed space in the gut.
LUMEN
What tissue part is this:
- Layer nearest to the lumen. It is thrown into a series of folds. This layer secretes mucus.
MUCOSA
What tissue part is this:
- Layer located around the mucosa.
SUBMUCOSA
What tissue part is this:
- composed of LONGITUDINAL and CIRCULAR MUSCLES.
VISCERAL MUSCLE LAYER
What tissue part is this:
- Outermost covering of the organ examined.
SEROSA
What is SEROSA?
OUTERMOST COVERING OF THE ORGAN
What is MUCOSA?
- LAYER NEAREST THE LUMEN
- THROWN IN A SERIES OF FOLDS
- SECRETES MUCUS
What is SUBMOCOSA?
LAYER LOCATED AROUND THE MUCOSA
What is the VISCERAL MUSCLE LAYER?
- COMPOSED OF LONGITUDINAL and CIRCULAR MUSCLES
These are COVERING tissues found OUTSIDE the anima, lining the digestive track and glands, and at the SURFACE of organs.
EPITHELIAL TISSUES
They are densely packed cells with little intercellular or interstitial matrix (space between cells).
EPITHELIAL TISSUES
What are the TWO (2) TYPES of EPITHELIAL TISSUES?
SIMPLE and COMPOUND EPITHELIUM
Consists of a single layer of cells.
SIMPLE EPITHELIUM
Consists of a series of layers which function as a PROTECTIVE COVERING for underlying tissues. Usually found in areas of heavy wear and tear where they provide rapid replacement of damaged cells.
COMPOUND EPITHELIUM
A layer of flat cells. They have high surface area and possess very little intracellular material.
SQUAMOUS EPITHELIUM
Similar to squamous cells but they are square- or cubed- shaped. They are usually found in the kidney.
CUBOIDAL EPITHELIUM
Where is the CUBOIDAL EPITHELIUM usually found?
KIDNEY
