Epithelial Characteristics
Epithelial Tissue is Avasuclar but Innervated. Meaning it gets its nutrients from nerve fibers in the _________.
Underlying CT
All CT have these 3 things.
Cells, Ground Substance, Fibers
This tissue uses Goblet Cells to secrete mucous and uses Cilia/Microvili to move it around your Upper Respiratory Tract.
Pseudostratified Columnar Epithelial
Aerolar Connective Tissue
This tissue does not have much ground substance because it consist of mostly adipocytes that cushion and support the body.
Adipose Connective Tissue
What are two functions of Epithelial Tissue?
Protection, Absorption, Filttration, Secretion, Excretion, Sensation
Cells ending in "________" are mature cells.
Cells ending in "________" are immature cells.
Immature - "Blasts"
This tissue lines your urinary organs to allow stretch when the bladder fills. The basal cells are cuboidal and the apical cells vary in shape.
Transitional Epithelial
The three types of Muscular Tissue are _________, _________, and __________.
Which ones are voluntary and which are involuntary?
Smooth, Skeletal, and Cardiac.
Voluntary: Skeletal
Involuntary: Smooth, Cardiac
The only fluid connective tissue is __________. Its ground substance is a thick fluid called _______ ________.
Blood; Blood Plasma
The polar surface of Epithelia is not attached to the tissue itself. This surface is exposed and faces the exterior/lumen of the cell.
Apical Surface
The three fiber types are _________, __________, and _________.The shortest and most branched fiber of the three are ____________ Fibers.
Collagen, Reticular, Elastic; Reticular
This tissue secretes and filters substances in your kidney tubules and glands (sweat, salivary).
Simple Cuboidal Epithelial
This Cartilage looks like pieces of glass under a microscope. It can be found in Epiphyseal Plates, Nose, and Ribcage and functions in smooth but firm movement.
Hyaline Cartilage
Elastic Cartilage can be found in the _______ and _________.
Ear and Epiglottis
All Epithelial Tissue has a Basement Membrane found on the Basal Surface. What two layers make up the Basement Membrane?
Basal Lamina & Reticular Lamina
What are two examples of immune cells?
Leukocytes (Neutrophils, Lymphocytes, Monocytes, Eosinophils, Basophils)
Mast Cells
Macrophages
This tissue has keratinized apical cellls, which means it is tough and protects us from friction and water loss. You can find this tissue in a lot of places, but most importantly in the epidermis of your skin.
Stratified Squamous Epithelia
This tissue is full of fibers that are very short and highly branched. This tissue is mostly found in the Lymph organs and Bone Marrow and functions in structural support for the body.
Reticular Connective Tissue
Fibrocartilage uses its thick collagen fibers to absorb shock and intense compression. It is found where in the body? (2 Places)
Intervertebral Discsc and Menisus of the Knee.
The function of the Basal Lamina is ___________.
The function of the Reticular Lamina is _________.
Basal Lamina - Resist tearing and stretching
Reticular Lamina - Holds lower tissues together
The primary function of elastic fibers is to stretch without breaking. A lot of these fibers can be found in what tissue?
Elastic Dense CT & Elastic Cartilage
This tissue is responsible for gas exchange in the lungs and kidney filtration. It's single layers can also be found lining blood vessels and body cavities.
Simple Squamous Epithelial
The bony matrix of Osseous Tissue is called what?
Lamellae
Dense Regular CT can be found where? Compared to Dense Irregular CT which is found where?
Dense Regular CT: Tendons, Ligaments
Dense Irregular CT: Dermis of skin
