GENBIO - Animal Tissue Flashcards
A group of cells with similar structure, functions, and origin working together is called
TISSUES
In animal body, they have been classified based on the type of cell, function, and location in the body
ANIMAL TISSUE
Four Basic Type of Animal Tissue
- EPITHELIAL
- CONNECTIVE
- MUSCLE
- NERVE
This tissue has a free surface.
EPITHELIAL TISSUE
It faces either a body fluid or the outside environment.
EPITHELIAL TISSUE
It provides a covering or a lining for some part of the body.
EPITHELIAL TISSUE
It forms the outer layer of the body and lines internal organs.
EPITHELIAL TISSUE
FUNCTION OF EPITHELIAL TISSUE
- Protective barrier
- Absorption
- Secretion
- Sensation
Skin
EPITHELIAL TISSUE
Lining of the mouth and nose
EPITHELIAL TISSUE
Lining of digestive system
EPITHELIAL TISSUE
In Epithelial Tissue, the cells of the tissue are closely connected to each other via __________.
Cellular Junctions.
Two distinct surfaces of Epithelial Tissue
- Apical Surface
- Basal Surface
It is exposed to the body cavity or exterior.
Apical Surface
MODIFIED TRUE OR FALSE
Basal surface is adjacent to the underlying tissue
TRUE
It is adjacent to the underlying tissue.
Basal surface
Two Types of Epithelial Tissues
- Simple epithelium
- Compound epithelium
Describe Simple squamous epithelium
- Plate like cells
- For exchange of material through diffusion
Capillaries and blood vessels are examples of ___________.
Simple squamous epithelium
This simple epithelial is a shape like dice.
Simple Cuboidal Epithelium
Simple Cuboidal Epithelium is used for _______.
For secretion
It is composed of a single layer of cells and functions as a lining for body cavities, ducts, and tubes.
Simple Epithelium
It consists of two or more cell layers and has protective function as it does in our skin.
Compound Epithelium
It is similar to simple cuboidal epithelium but with added cilia
Simple Cuboidal Ciliated
It lines the terminal bronchioles and respiratory bronchioles
Simple Cuboidal Ciliated
Describe Simple Columnar Epithelium
- Brick-shaped cells
- For secretion and active absorption
It lines the fallopian tube and the endometrium of the uterus.
Simple Columnar Ciliated
It may look stacked because of varying
height.
Pseudo- stratified columnar
Pseudo- stratified columnar usually have______.
Cilia
Kind of Compound Epithelial that its surface cells remain moist and are not hardened by keratin.
Stratified Squamous, non keratinized
Stratified Squamous, non keratinized is a __________________.
Multilayered and regenerate quickly
Stratified Squamous, non keratinized is used for _____________.
For protection against abrasion and friction
This compound epithelial helps protect the underlying tissues from the wear and tear caused by the passage of food and liquids.
Stratified Squamous, non keratinized
The superficial cells have a layer of keratin, a tough, protective protein, which makes the surface dry and resistant to abrasion and water loss.
Stratified Squamous, Keratinized
They are all characterized by the presence of extracellular matrix.
CONNECTIVE TISSUE
It is the nonliving material composed of protein fibers and ground substance.
Extracellular Matrix
Extracellular Matrix is composed of
Fibers and Ground Substance
It holds organs in place
Loose Connective Tissue
Made up of collagenous fibers found in tendons and ligaments.
Fibrous Connective Tissue
Fibrous Connective Tissue consists of
Collagen
Fibrous Connective Tissue is used to _____________.
Provide strength and
stability
Ligaments is an example of __________.
Fibrous Connective Tissue
Tendons is an _________.
Fibrous Connective Tissue
It is a firm matrix with abundant collagen fibers.
Cartilage
Cartilage provides ___________.
Structural support and cushioning properties
It forms the skeletal system
BONE
Bone provides ____________.
- Provide structural support
- Protection
- Mineral storage
Made up of plasma, contains water, salts and dissolved proteins.
Blood
Blood consists of __________.
*White Blood Cells
*Red Blood Cells
* Platelets
They are composed of long cells called muscle fibers.
MUSCLE TISSUE
It allow the body to move voluntary or involuntary
MUSCLE TISSUE
Muscle Tissue are composed of long cells called _________,
Muscle Fibers
Muscle Tissue is specialized for ________.
Contraction
Mucle Tissue contains ____________________.
*Contractile proteins actin
*Myosin
It is a long, cylindrical cells with multiple nuclei and striations (striped appearance).
Skeletal Muscle Tissue
Its function is to do voluntary control of
movement; responsible for moving bones and facilitating movement
Skeletal Muscle Tissue
It is a branched cells with a single nucleus per cell, striations, and intercalated discs (specialized junctions
between cells).
Cardiac Muscle Tissue
Its function is to do involuntary control; it contracts to pump blood through the heart and into the circulatory system.
Cardiac Muscle Tissue
Cardiac Muscle Tissue can only be found in the __________.
Heart
It is a spindle-shaped cells with a single nucleus and no striations.
Smooth Muscle Tissue
Its function is to do Involuntary control; it regulates the movement of internal organs by contracting and relaxing.
Smooth Muscle Tissue
This muscle tissue can be found in the walls of hollow organs.
Smooth Muscle Tissue
They are composed of nerve cells called neurons and glial cells.
NERVE TISSUE
In nerve tissue, neurons communicate with each other via ______________.
Electrical and Chemical Signals
TWO TYPES OF ELONGATED CELLULAR PROCESSES
- Dendrites
- Axons
This send the signals.
Axons
This receives the signals.
Dendrites
