Connective Tissue
What are two of the functions of connective tissues?
support, protection, framework, fills space, stores fat, produces blood cells, fights infection
Where can epithelial tissues be found?
Covering all body surfaces inside and out
All muscle tissues have the ability to ________, which means to shorten
Contract
Nervous tissue is found where
the brain, spinal cord, and peripheral nerves
Define tissues
a group or mass of similar cells working together to perform similar functions.
What are the three types of cells within the connective tissues?
Mast cells (prevents clots)
Macrophages (consumers)
Fibroblasts (produce fibers)
Epithelial tissues are categorized into two main groups based on the _____ of their cells and their #'s of ______ of cells.
shape, layers
Skeletal and cardiac are two of the three types of muscle tissue. What is the third?
Smooth
Describe the structure (shape) of a typical nerve cell
The primary components of the neuron are:
the soma (cell body), the axon (a long slender projection that conducts electrical impulses away from the cell body), and dendrites (tree-like structures that receive messages from other neurons)
Which tissue type can change under tension?
Transitional epithelium
Name 3 examples of connective tissues
Blood, bone, cartilage, adipose, loose (under the skin), tendons, ligaments
Identify the three types of simple epithelial tissues AND their functions.
Simple Squamous- diffusion & filtration
Simple Cuboidal- secretion and absorption
Simple Columnar- secretion and absorption
Skeletal muscle tissue differs from the other types as it is considered to be under _______ control.
Voluntary
The function of nervous tissue is __________.
Cell-to-cell communications
Send and receive messages between brain and body
Which muscle type(s) have striations?
Skeletal and cardiac
Connective tissue that stores fat
Adipose tissue
Where can you find the Pseudostratified Columnar tissues, and what is their function?
They line the air-passages and the tubes in the reproductive system.
Their function is secretion and cilia-aided movement
Smooth muscle tissue comprises the walls of what organs?
Hollow internal organs such as the stomach, intestines, urinary bladder, uterus, and blood vessels.
Along with neurons, nervous tissue includes abundant ______ cells. These cells support and bind the components of nervous tissue.
Neuroglial
Which type of cartilage is located between the vertebrae and bones of the knee
Fibrocartilage
How many different types of cartilage are there, what are they, and where can they be found?
3
1. Hyaline cartilage- ends of joints/bones
2. Elastic cartilage- external ear and tip of nose
3. Fibrocartilage- between vertebrae and knees
All epithelial tissues attach here.
Connected to the connective tissues at the basement membrane.
The intercellular junction (where two cells meet) is only found in cardiac tissues and is called ____.
Intercalated disc
Using the handout provided, which tissue is an example of a nervous tissue?
D
Which epithelial tissue forms the skin?
Stratified squamous
