Introduction to Tissues
What are the four basic types of tissues found in the human body?
Epithelia | Connective |Muscular |Nervous
Epithelial tissues are classified by the ______and_________.
Number of cell layers & The cell shape
Connective tissue proper is divided into _____ and _____.
Loose and Dense
This type of tissue is striated, cylindrical, and multinucleated fibers.
Skeletal Muscle Tissue
The two types of cells that compose nervous tissue are ____ &______.
Neuron and Neuroglia (supporting cells).
These types of glands have no ducts and release hormones that enter bloodstream.
Endocrine Glands
This is the most diverse tissue in the human body ranging from blood to bone and everything in-between.
These type of epithelial tissue have multiple layers and are cube shaped.
Stratified cuboidal epithelia
This type of connective tissue stores energy, insulates the body and cushions organs.
Adipose (Connective Tissue Proper)
True or False: Skeletal muscle is involuntary
False: Voluntary (you consciously control their movement).
This the part of the Neuron that is composed of short branches extending from the cell body and receive incoming signals
Dendrites
________feature a main, unbranched excretory duct that connects directly to the secretory units.
Simple Exocrine Glands
This type of tissue forms the protective outer coverings of the body, lines internal cavities and organs, and makes up glandular tissue.
Epithelia
True or False Epithelia tissue are: closely packed cells, vascular and are polar cells
False: Epithelia cells are avascular = contain no blood vessels
Tendons | Ligaments
This tissue is striated, branching fibers connected by specialized junctions called intercalated discs.
Cardiac Muscle Tissue
These are classified as the "support staff". They do not transmit nerve impulses but instead bind neurons together, provide electrical insulation, deliver nutrients, and remove waste
Neuroglia (Glial Cells)
These glands are composed of the tubular secretory section bifurcates into multiple branches sharing the same duct, found in the gastric and uterine glands
Simple branched tubular
______ & ________ are specialized fluid connective tissues that circulate throughout the body to connect vital systems, transport nutrients and wastes, and defend against pathogens
Blood & Lymph
You would expect to find these type of Epithelial tissue in the urinary bladder.
Transitional (to accommodate stretching due to volume fluctuations).
Highly flexible, containing a dense network of branching elastic fibers. Provides both strength and shape retention, primarily found in the external ear and epiglottis.
Elastic Cartilage
This tissue is non-striated, spindle-shaped cells with a single nucleus and located in hollow organs (stomach, intestines, bladder), blood vessels, and respiratory/reproductive tracts
Smooth Muscle Tissue
This is the part of the Neuron that is composed of a long, thin extension of the cell body. Main function includes carrying outgoing electrical signals to their destination
Axon (Nerve Fiber)
These glands are typically larger, bulkier, and feature an elaborate, tree-like branching duct system.
Compound Exocrine Glands
_______ is the scientific study of the microscopic anatomy of biological tissues and cells.
Histology
The epidermis of the skin is made up of ______ epithelia to provide physical protection against abrasion
Stratified squamous epithelial tissue
______ is a rigid, calcified connective tissue that forms the skeletal framework.
Bone
Muscle tissue is composed of excitable cells packed with contractile proteins ______&______ that shorten to facilitate locomotion, pump blood, and propel substances through internal organs
Actin and Myosin
Most neurons live for an entire lifetime, often surviving for how many years?
90 years or more
This is a type of glandular secretion gathers in the top portion of the cell. Examples include Mammary glands and apocrine sweat glands in the armpits and groin.
Apocrine Secretion
