Animal Tissues Flashcards
what is connective tissue mostly composed of?
non-living materials (ground substance - extracellular matrix - jelly-like substance)
what loose connective tissue serves as the fat reservoir and thermal insulator.
adipose/fat tissue
one layer, elongated or column-shaped epithelial tissue
- for absorption and secretion; contain goblet cells that secrete mucus
walls of
- present in the gastro-intestinal tract and body
cavities
simple columnar epithelial tissue
the basic unit of the nervous system,
consists of structures that can conduct
electrochemical signals as a form of information.
neuron (nerve cell)
Connective tissue with a matrix that contains more cells and lesser fibers than dense connective tissue so it is softer.
- for protection, insulation, storage and support
- examples are areolar and adipose tissue
loose connective tissue
connective tissue that has a plasma
- Cellular components consist
of blood cells.
- with fibers that are only visible during
clotting because they are made up of
soluble proteins
- for transport of substance, immune response, and blood clotting
- blood and blood cells
blood
highly branched fibers which form a delicate network in organs that have lots of mesh-like internal structure.
-short finer collagen fibers
- sponge like
reticular fibers
nervous tissue
These are responsible for the production of the
myelin sheath.
- CNS
oligodendrocytes
nervous tissue
These are ciliated cells that line the central cavities of the brain and the spinal cord and form
a fairly permeable membrane between the cavities with cerebrospinal fluid and the tissues of
CNS.
ependymal cells
what loose connective tissue fills the space between organs, supporting internal organs
areolar tissue
types of muscular tissue
skeletal, smooth, and cardiac
bone cells
osteocytes
cartilage cells
chondrocytes
Connective tissue where the Matrix is predominantly made up of collagen fibers
and has lesser cells.
- This is a fibroblast or a fiber-forming cell.
- for support
- examples are tendons and ligaments
dense connective/dense fibrous tissue
more than one layer, elongated or column-shaped epithelial tissue
- for protection and secretion
- male urethra and ducts of some glands
stratified columnar epithelium
What connects your muscles to your bones?
Tendons
tissues that bind structures together, form a framework and support for organs and the body as a whole, store fat, transport substances, protect against disease, and help repair tissue damage.
connective tissue
muscle tissue
made up of nonstriated, uninucleated, and spindle-shaped (have pointed ends) cells.
-found in the walls of hollow organs such as intestines, stomach, bladder, blood vessels, and uterus
- involuntary
smooth muscle
form of extracellular matrix that underlies all epithelia. It provides structural support to epithelia and forms a mechanical connection between epithelia and underlying connective tissue.
basement membrane
nervous tissue
These are cells in the CNS that can transform into a phagocytic macrophage to clean neuronal debris and wastes.
microglial cells
muscle tissue
long, cylindrical, striated (with
visible stripes), and multinucleated
(with more than one nucleus)
- attached to the skeleton or bone
- voluntary
skeletal muscle
These refer to groups of cells that are similar in structure and function.
Tissue
a type of animal tissue that forms the inner
and outer lining of organs, the covering
in surfaces, and the primary glandular
tissue of the body.
epithelial tissue
more than one layer, flat, scale-like epithelial tissue
- for protection against abrasion or constant exposure to friction
- present in the epidermis, lining of
mouth, esophagus, and vagina
stratified squamous epithelium
nervous tissue
They surround all the nerve fibers and
produce myelin sheath similar to the
oligodendrocytes.
- PNS
schwann cells
more than one layer, cube-shaped epithelial tissue
- for protection and secretion
- present in sweat glands, salivary glands,
and mammary glands
stratified cuboidal epithelium
tiny fibers that can stretch and recoil and they are found in elastic tissues.
elastin/c fibers
in this cartilage, the chondrocytes are found in a threadlike network of elastic fibres within the matrix.
- provides strength, and elasticity, and maintains the shape of certain structures such as the external ear. It has a perichondrium.
elastic cartilage
muscle tissue
made up of nonstriated, uninucleated, and spindle-shaped (have pointed ends) cells.
-found in the walls of hollow organs such as intestines, stomach, bladder, blood vessels, and uterus
- involuntary
smooth muscle tissue
What connects bone to bone, give your joints support, and limit their movement.
Ligaments
This is the strongest kind of cartilage, because it has alternating layers of hyaline cartilage matrix and thick layers of dense collagen fibres oriented in the direction of functional stresses.
This type of cartilage does not have a perichondrium as it is usually a transitional layer between hyaline cartilage and tendon or ligament.
-is found in invertebral discs, joint capsules, ligaments
fibrocartilage
This type of cartilage has a glassy appearance when fresh, hence its name, as hyalos is greek for glassy.
- most common
- found in the ribs, nose, larynx, trachea. Is a precursor of bone.
- It has a perichondrium, and it is the weakest of the three types of cartilage.
hyaline cartilage
one layer, cube-shaped epithelial tissue
- for absorption and secretion
- present in glands and their ducts, ovaries, and lining of kidney tubules
simple cuboidal epithelial tissue
muscle tissue
- uninucleated (one nucleus) and has striations
- has intercalated disks
- found in the heart
- involuntary
cardiac muscle
stratified tissue made of multiple cell layers, where the cells constituting the tissue can change shape depending on the distention in the organ. When the organ is filled with fluid, cells on the topmost layer of this epithelium can stretch and appear flattened. Alternately, they can also appear cuboidal with a rounded shape when the fluid pressure is low.
transitional epithelium
the most abundant type of fibers in the extracellular matrix of connective tissues
collagen fibers
nervous tissue
These are star-shaped cells that support and control the chemical environment around
the neurons.
These are the most abundant glial cell in the CNS.
astrocytes
types of connective tissue
bones, cartilage, loose, dense, blood
Main types of Animal Tissue
- epithelial tissue
- connective tissue
- muscular tissue
- nervous tissue
one layer, flat scale-like epithelial tissue
- site of diffusion/exchange of substances (filtration)
- secretion
- present in air sacs/alveoli, capillary walls
simple squamous epithelial tissue
nervous tissue
They surround the cell body of a neuron.
- PNS
satellite cells
connective tissue with layers of a very hard matrix with calcium salts and collagen fibers
- for protection and support
bone or osseous tissue
connective tissue with a more flexible matrix than
bone
- for protection and support
- examples are hyaline, fibro, and elastic ________
cartilage
what is the most abundant and diverse tissue?
connective tissue
one layer, elongated or column-shaped epithelial tissue
- for absorption and secretion; usually ciliated;
cells have unequal length and position of
nucleus forming a false layering of cells
- present in the lining of the respiratory tract
pseudostratified columnar epithelial tissue
tissue that is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities. It stimulates muscle contraction, creates an awareness of the environment, and plays a major role in emotions, memory, and reasoning.
nervous tissue
tissue that is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.
muscular tissue
