ANIMAL TISSUE
SUMMARY
| Question | Answer |
|---|---|
| are similar in structure group together to form tissues performing a particular function. | CELLS |
| ANIMAL TISSUES ARE MADE UP OF | - epithelial - connective - muscle - nerve tissue. |
| Epithelium is made up | - flat squamous cells - cuboidal cells - columnar cells |
| involved in secretion of enzymes, protective substances such as mucus and they provide a supportive function. | epithelial cells |
| Muscle tissue is made up of | - cardiac muscle - skeletal muscle - smooth muscle. |
| are striated muscles | Cardiac and skeletal muscle |
| are involuntary muscles | Smooth muscle and cardiac muscle |
| is under voluntary control. | skeletal muscle |
| Connective tissues are composed of | - connective tissue proper - fluid connective tissue - supporting connective tissue |
| They provide strength and support, reduce friction and act as a shock absorbers. | connective tissues |
| made up of red blood cells, white blood cells, and platelets | blood |
| transport oxygen | red blood cells |
| responsible for immune response | white blood cells |
| important in blood clothing | platelets |
| responsible for receiving stimuli from the environment, processing it and sending impulses to muscles or glands so that we can respond to the stimuli. | Nerve tissue |
| sensory neurons | stimuli |
| Cells that come from surfaces of your body, such as your skin, blood, vessels, urinary tract, or organs. | Epithelial cells |
| serve as a barrier between the inside and outside of your body, and protect it from viruses. | Epithelial cells |
| Grouped together to make our skin. | Epithelial cells |
| Cannot formed if epithelial is absorbing. | Bone tissue |
| covers by apical | basal |
| CLASSIFICATION OF EPITHELIAL CELLS | - Number of cell layers - The shape of the superficial cells |
| With its single layer of cells, covers surfaces. | Simple epithelium |
| it facilitates the diffusion of gases | lungs |
| filters blood | kidney |
| secretes cellular products | glands |
| it absorbs nutrients | intestines |
| More than one layer and one on top of another. | Stratified epithelium |
| Is found in areas of the body where abrasion can occur | Stratified squamous epithelium |
| found in skin, mouth throat, esophagus, anus, and vagina. | Stratified squamous epithelium |
| Looks like have on more than layer but does not. | Pseudo stratified |
| CHARACTERISTICS THAT ARE USED TO CLASSIFY TISSUE | - The structure of the cells. - The composition of the noncellular substances surrounding the cells - The functions of the cells. |
| The composition of the noncellular substances surrounding the cells | extracellular matrix |
| Covers and protects surface from outside and inside. | Epithelial tissues |
| Binds and support the organs, provides protection, participates in immunity. | Connective tissues |
| Enclose and separate muscles, arteries, veins, and nerves from one another. | Connective tissues |
| Responsible for movement. | muscle tissues |
| Reside stimuli, conducts nerves and pulses. | nervous tissues |
| are most diverse in form base on number of cells layers. | Epithelial and connective tissues |
| cell shape | cell layer |
| FUNCTIONS OF CONNECTIVE TISSUE | - structural support - connection - protection - blood |
| Attach muscles to bone. | tendons |
| Holds bone together. | ligaments (bands) |
| Provide rigid support for the body. | bones |
| Supports structures such as the nose, ears, and joint surfaces. | cartilage |
| how many cartilage in adult | 206 |
| how many cartilage in human infants | 270 |
| Between bones allow one part of the body to move relative to other parts. | joints |
| Stores high energy molecule. | Adipose tissue |
| Loosely arrange collagens and fibers | Adipose tissue |
| The specialized cells of the various connective tissues produce the extracellular matrix. | CELLS OF CONNECTIVE TISSUE |
| create matrix | blast |
| cytes | cell |
| break it down | Clasts |
| are cells that form fibrous connective tissue. | fibroblast |
| form cartilage | CHONDROBLASTS |
| chondro means | cartilage |
| form bones | OSTEOBLASTS |
| osteo means | bones |
| Supports, protects, and hold bones, muscles, and other tissues and organs in place. | dense connective tissue |
| Type of cell that contributes to the formation of connective tissue. | fibroblast |
| Has protein fibers in the extracellular matrix that are oriented predominantly in one direction. | Dense regular connective tissue |
| have collagen fiber | Collagenous connective |
| It connects our bones to bones. | ligaments |
| helping to hold our head upright | Nutra ligaments |
| Protein fibers, arranged randomly, layers oriented right angle, many direction | Dense irregular tissue |
| no blood vessels or nerves | Cartilage |
| Transport oxygen, carbon dioxide, hormones, nutrients, waste products, and other substances. | red blood cells |
| Protects the body from infections and is involved in temperature regulation | white blood cells |
| Form cloths and stop or prevent bleeding. | platelets |
| Is found in the brain, spinal cord, and nerves and is characterized by the ability to conduct electrical signals called action potentials. | nervous tissue |
| are responsible for its conductive ability and support cells called neuroglia. | neurons |
| Are the conducting cells of nervous tissue. | Neurons or nerve cells |
| projection in cytoplasm, surrounded by membrane | Axon |
| receive action potential (conducts electrical signals) | Dendrites |
