Gen Bio Quiz 2 (Animal Tissues) Flashcards
presence of basement membrane
epithelial
binds the epithelium together and separates from underlying connective tissue
Basement membrane
It consists of closely packed sheets of cells covering surfaces- including the outside of the body- and cavities of the body wall.
Epithelial tissue
It is a tissue that can be found in the outer layer of your skin such as in the lining of your small intestine.
Epithelial tissue
It lines the heart, blood, and lymphatic vessels, body cavities, and alveoli.
Simple squamous
It lines the kidney tubules and covers ovaries.
Simple cuboidal
It is elongated cells and ciliated, lines most organs of the digestive tract including the stomach, and intestines.
Simple columnar
Some of its cells are shorter than others, and their nuclei appear at different heights above the basement membrane
Pseudostratified columnar
It protects against abrasion; esophagus, mouth, and outer portion of the skin.
Stratified squamous
It supports and binds other tissues.
Connective Tissue
The most abundant and widely distributed tissues that also functions as protection.
Connective Tissue
It is made up of cells that are suspended in an
extracellular matrix.
Connective Tissue
What are the 3 types of connective tissue fibers?
- Collagenous
- Reticular
- Elastic
It is a type of CT fiber that provides strength and flexibility.
Collagenous
It is a type of CT fiber that joins connective tissue to adjacent tissue; forms the internal skeleton.
Reticular
A CT fiber that makes tissues elastic
Elastic
What are the types of connective tissue?
- Dense CT
- Loose CT
- Bone
- Blood
- Cartilage
What are the types of cartilage?
- Hyaline
- Elastic
- Fibrocartilage
also called osseous tissue
bone
the matrix of _____ is calcified by calcium salts organized around collagen fibers arranged in concentric rings (lamella)
bone
It has an exceptional ability to protect and support other body organs (for example, the skull protects the brain) because of its rocklike hardness.
bone
cavities where bone cells are lodged
Lacunae
bone cells
Osteocytes
The main matrix of this type of CT is collagen fibers
Dense fibrous tissue
This tissue is found in
tendons and ligaments
Dense fibrous tissue
a fibrous tissue that connects bones to bones at joints
Ligaments
a fibrous tissue that attaches skeletal muscles to bones
Tendons
It is the most widely distributed connective tissue variety in the body, is a soft, pliable, “cobwebby” tissue that cushions, wraps, and protects the body organs from falling.
Areolar LCT
Functions as a universal packing tissue and connective tissue “glue” because it helps to hold the internal organs together and in their proper positions.
Areolar LCT
What are the types of loose CT?
- Areolar
- Adipose
- Reticular
It is characterized by relatively loosely arranged collagen and elastic fibers.
Areolar LCT
It is highly cellular, containing fibroblasts, immune cells (e.g., mast cells, macrophages, T cells), and endothelial cells.
Areolar LCT
It is often found directly underlying epithelia that cover body surfaces or line internal surfaces.
Areolar LCT
Commonly known as fat
Adipose LCT
It cushions, supports, insulates and acts as filler tissue.
Adipose LCT
Its main role is to serve as an energy storing reservoir, but it also insulates the body from extreme temperatures, cushions vital organs, and secretes hormones and biological factors.
Adipose Tissue LCT
It is mostly present during fetal life and in infants.
Brown Adipose Tissue
It forms the stroma (literally, “bed” or “mattress”), or the internal framework of an organ.
Reticular Tissue LCT
The _______ is mostly made up of connective tissue, blood vessels, lymphatic vessels, and nerves.
stroma
a type of connective tissue with a network of reticular fibers, made of type III collagen
Reticular connective tissue
Reticulum = ?
net or network
It serves as the supporting structure of the bone marrow, liver and lymphoid organs (spleen, lymph nodes, and tonsils).
Reticular connective tissue
Blood is surrounded by a nonliving, fluid matrix called ________ and the formed elements ( cells, corpuscles, and fragments)
blood plasma
The ______ of blood are soluble protein molecules that become visible only during blood clotting.
fibers
It is a specialized fluid connective tissue consisting of some cells suspended in a liquid intercellular substance known as plasma.
Blood
It is considered as specialized connective tissue as it connects all systems of the body.
blood
What are the 2 parts of blood?
Plasma and blood cells
It supports the external ear
Elastic cartilage
It is the most flexible cartilage and it supports parts of your body that need to bend and move to function.
Elastic Cartilage
It forms the supporting structures of the larynx, or voice box, attaches the ribs to the breastbone, and covers the ends of many bones
Hyaline cartilage
It forms the cushion-like disks between the vertebrae of the spinal column
Fibrocartilage
It is found predominantly in the intervertebral disks of the spine and at the insertions of ligaments and tendons.
Fibrocartilage
Its main function is to act as a cushion within joints, where it helps manage compression forces and reduces stress placed on joints.
Fibrocartilage
spindle-shaped fibers
smooth MT
Its fibers seem to anastomose with adjacent ones
cardiac MT
elongated with multi-nucleated fibers, alternating dark and light bands
skeletal MT
specialized to receive and transmit impulses from one part of the body to the other parts.
neurons
It supports the nerve cells
Neuroglial Cells
What are the types of muscle tissue?
- Skeletal
- Smooth
- Cardiac
A tissue that is responsible for receipt, processing, and transmission of information.
Nervous tissue
This tissue helps in movement and locomotion, supports the bones and other structures,
and it’s also responsible for peristalsis and parturition.
Muscular tissue
a tissue that is responsible for voluntary movements and attached to bones by tendons
Skeletal
It lacks striations, and is found in the walls of the digestive tract, urinary bladder, arteries, and other internal organs.
Smooth
It forms the contractile wall of the heart.
Cardiac
It has branched fibers that interconnect via intercalated disks, which relay signals from cell to cell and help synchronize heart contraction.
Cardiac
It develops from the ectoderm of the embryo and it possesses the ability to initiate and transmit the nerve impulse.
Nervous Tissue
receive impulses from other neurons
Dendrites
transmit impulses to neurons, muscles, or other cells
Axons
These are the structural and functional unit of nervous system.
Neurons
These are special cells found in the brain and spinal cord. They also provide support to the neurons and fibers.
Neuroglia
These function as endocrine organs that releases chemical from the axons directly into blood.
Neurosecretory Cells
It is concerned with the transmission of impulses, specialized to receive and transmit impulses from one part of the body to the other parts.
Nervous Tissue
This tissue exhibits syncytium and striations or striae
Muscle Tissue
