Epithelial
This ET is a single layer of cube-like cells with large, spherical nuclei.
It functions in secretion and absorption.
It is located in the renal tubules, ovarian follicles, and thyroid glands.
What is simple cuboidal ET?
This type of CT develops from mesenchyme is the fluid in blood vessels. It is the most atypical CT and does not bind things together or give mechanical support.
What is blood connective tissue?
This type of Muscle Tissue is voluntary and are usually long, large cylinders that contain many nuclei. They have obvious striations and function in locomotion, the manipulation of the environment, facial expression, and voluntary controls and movements.
What is Skeletal Muscle Tissue?
This type of membrane is the skin covering the outer surface of the body. It consists of the epithelium which is the outer epidermis (stratified squamous ET) and connective tissue proper which is the underlying dermis (loose areolar CT and dense irregular CT).
What is Cutaneous Membrane?
These are finger-like extensions of plasma membrane. They contain a core of actin microfilaments and function to increase surface area across which small molecules enter or leave.
What is microvilli?
This is a single layer of column-shaped cells that allows for secretion and absorption.
Non-ciliated form is located in the majority of the digestive tract and the gallbladder.
Ciliated form is location in the uterine tubes and uterus, along with the small bronchi.
What is simple columnar?
This type of CT is firm, flexible tissue. It contains no blood vessels or nerves. The matrix contains up to 80% water and consists of chondroblasts and chondrocytes.
The three types of this CT are Hyaline, Elastic, and Fibro-.
What is Cartilage Connective Tissue?
This type of muscle tissue is involuntary and is spindle shaped with one centrally located nucleus. Found mostly in the walls of all hollow viscera and functions to propel substances or objects along internal passageways.
What is Smooth muscle?
This membrane lines the inside of every hollow internal organ that opens to outside of body. They are wet and moist and lines the tubes of the respiratory, digestive, reproductive, and urinary systems and consists of an epithelial sheet directly above a layer of loose connective tissue proper called lamina propria.
What are mucous membranes?
What is Cilia?
All of the stratified ET are all for the function of protection.
These type of multiple layer (usually two) of cube-like cells are located in the ovarian follicles, seminiferous tubules, and salivary glands.
What is Stratified Cuboidal ET?
This type of CT has fiber bundles with not a lot of ground substance in between.
The types of CT in this category are regular, irregular, and elastic.
What is Dense Connective Tissue Proper?
This tissue functions to transmit electrical signals from sensory receptors and to effectors that control the activity of effector organs.
What is nervous tissue?
This type of exocrine gland has two basic parts: epithelium-walled duct and secretory unit. The structure of the duct is either simple or compound and the secretory unit is structured as either tubular, alveolar, or tubuloalveolar.
What is multicellular exocrine gland?
This is one of the six special characteristics of ET that states the tissue has no blood vessels but has nerves. This means the nutrients are brought by capillaries from underlying connective tissue.
This type of ET with basal cells that usually looks cuboidal or columnar but has superficial dome-shaped or squamous cells. This permits distention or stretching.
Located in the lining of the ureters and the urinary bladder.
What is Transitional Epithelium?
This type of CT has fibers distributed throughout tissue and separated by ground substance.
The three categories of this type of CT are Areolar, Reticular, and Adipose.
What is Loose connective tissue proper?
This muscle tissue is somewhat elongated and found only in the wall of the heart. It has less pronounced striations and each cell generally has one nucleus. It also contains a special cellular junction called intercalated discs. It functions to contract, propels blood into circulation and is involuntary control.
What is Cardiac muscle?
This type of membrane is a slippery membrane that line the closed pleural, pericardial, and peritoneal cavities. It produces a slippery serous fluid and consists of a layer of simple squamous ET lying on a thin layer of loose areolar CT.
What is the Serous Membrane?
This type of cell junction is 2 disc-like plaques connected across intercellular space (via proteins called cadherins). Intermediate filaments insert into plaques from cytoplasmic side and function to resist tension. They are the main junctions for binding cells together.
What is desmosome?
All cells of this ET originate at basement membrane. The nuclei lie at varying heights within the cells making it look stratified. It functions in the secretion of mucus and propulsion of mucus by cilia.
Ciliated form lines the trachea and most of upper respiratory tract.
The non-ciliated form lines the ducts of male reproductive tubes and ducts of large glands.
This type of CT has a calcified matrix containing many collagen fibers and inorganic calcium salts. It contains osteocytes, osteoblasts, and osteoclasts. It is well vascularized and helps with support and protection. It is an attachment place for muscles for voluntary movement, stores calcium and other minerals, fats, and nutrients. The marrow inside is a site for blood cell formation.
What is Bone CT?
These are highly specialized cells that generate and conduct electrical impulses and release chemicals called neurotransmitters.
What are neurons?
This type of Exocrine gland, also known as the Goblet cell, is scattered throughout epithelial lining of intestines and respiratory tubes, between columnar cells. They produce mucin; covers, protects, and lubricates many internal body surfaces.
What is the unicellular exocrine gland?
This is the border between the ET and the underlying CT. It is a non-cellular supporting sheet of proteins secreted by ET cells and functions as a selective filter, determining which molecules from capillaries enter the epithelium. It also acts as scaffolding along which regenerating epithelial cells can migrate.
What is Basal Lamina?
