Epithelial Tissue
Glands built from epithelial tissue come in two types: this type releases secretions like sweat and saliva through ducts.
What are exocrine glands?
Connective tissue is made of scattered cells within this substance, which itself is composed of ground substance and fibers.
What is the matrix?
Cardiac, skeletal, and smooth are the three main types of this tissue.
What is muscle tissue?
Single layer, flat and thin. Function: diffusion and filtration. Found in air sacs of the lungs and capillaries.
What is simple squamous epithelium?
Epidermolysis bullosa causes severe blistering because anchoring fibrils between these two major skin layers are missing
What are the dermis and epidermis?
These cells are scattered throughout columnar tissue and function to secrete mucus
What are goblet cells?
Tendons connect bones to this structure.
What is muscle?
Cardiac muscle is found exclusively within this organ.
What is the heart?
Function: secretion and absorption. Found in kidney tubules, ducts, and covering the ovaries.
What is simple cuboidal epithelium?
The primary biological purpose of skin pigment produced by melanocytes is to protect cells from this type of radiation.
What is ultraviolet (UV) radiation?
To prevent pigment from being replaced by new skin cells over time, tattoo ink must be injected below this structure.
What is the basement membrane?
These cells of connective tissue function to consume invading bacteria and other foreign cells.
What are macrophages?
This primary cell type serves as the main structural and functional component of brain and nervous tissue.
What is a neuron?
Function: secretion and absorption. Found in the digestive tract and uterus.
What is simple columnar epithelium?
Patients with severe EB often experience extreme nutritional complications and need feeding tubes because this specific tissue lining the mouth and esophagus blisters and scars.
What is stratified squamous epithelium?
Extensions of the cell larger than cilia that are used for absorption are called this.
What are microvilli?
A droplet of oil is found within the cells of this tissue, which is used for energy storage.
What is adipose tissue?
These specialized helper cells provide support and protection for neurons
What are neuroglia?
Multi-layer squamous tissue, functions in protection. Found lining body cavities, skin, and the mouth.
What is stratified squamous epithelium?
These are the three main structural layers that make up human skin
What are the epidermis, dermis, and hypodermis?
This is missing in a person skin with EB disease
What are anchoring fibrils?
These specific cells are responsible for producing collagen and elastic fibers found in connective tissue.
What are fibroblasts?
Nervous tissue relies on these types of signals to carry out rapid body coordination and communication.
What are electrochemical signals?
Stretchable, blocks diffusion (no leaking). Found in the urinary bladder.
What is transitional epithelium?
These two primary cell types are part of the epidermis.
What are keratinocytes and melanocytes?
