Q

Epithelial Tissue

What are the four functions of epithelial tissue?

(hint: 4)

A
  1. Provide physical protection
  2. Control permeability
  3. Provide sensation
  4. Produce specialized secretions

  1. Epithelia protect exposed and internal surfaces from abrasion, dehydration, and destruction by chemical/biological agents.
  2. Any substances that enters or leaves the body must cross epithelium, therefore it must be regulated.
  3. Most epithelia are extremely sensitive to stimulation because they have a large sensory nerve supply.
  4. Epithelial cells that produce secretions are called gland cells.

Q

Epithelial Tissue

What are the characteristics of epithelial tissue?

(hint: 5)

A
  1. Polarity
  2. Cellularity
  3. Attachment
  4. Avascularity
  5. Regeneration

  1. Polarity meaning it has an apical (exposed) surface and basement membrane.
  2. Epithelia are made almost entirely of cells bound closely together by cell junctions.
  3. Base of epithelium is bound to a basement membrane.
  4. Epithelia lack blood vessels and get their nutrients from diffusion and absoprtion from other cells.
  5. Epithelial cells are continuously replaced through stem cell divisions in the epithelium.

Q

Epithelial Tissue

This type of epithelium acts as an exchange system, and is located in protected regions where absorption and diffusion takes place, or where a slick, slippery surface reduces friction.

A

Simple squamous epithelium

Reduces friction, controls vessels permeability, performs absorption/secretion.

# Connective Tissue Connective tissues vary widely in appearance and function, but they all share **three basic components**.
1. Specialized cells 2. Extracellular protein fibers 3. A fluid known as ground matrix
126
# Connective Tissue The specific function of connective tissues include: | (hint: 6)
**Functions:** 1. Establishing a structural framework for the body 2. Transporting fluids and dissolved materials 3. Protecting delicate organs 4. Supporting, surrouding, and interconnecting other types of tissue 5. Storing energy 6. Defending the body from invading microorganisms
127
# Connective Tissue We classify by their physical properties. The **three general categories** of connective tissue:
1. Connective tissue proper 2. Fluid connective tissue 3. Supportive connective tissue
128
# Connective Tissue What are the **three types of fibers** that are found in connective tissue?
1. Collagen fibers 2. Reticular fibers 3. Elastic fibers
129
# Connective Tissue **Identify the type of fiber:** The most common type of fibers in connective tissue proper. They are **long, straight, and unbranched**. Each fiber consists of a bundle of fibrous protein subunits wound together like the strands of a rope. It is **flexible** like a rope, and **stronger** than steel.
Collagen fibers
130
# Connective Tissue **Identify the tissue fiber:** Contains the same protein subunits as collagen fibers, but are arranged differently. Thinner than collagen, and form **branching, interwoven framwork that is tough, yet flexible**. They **resist forces in many directions** because they form a network.
Reticular fibers
131
# Connective Tissue **Identify the tissue fiber:** Contains the protein elastin. They are **branched and wavy**. After **stretching, they return to their original length**.
Elastic fibers
132
# Connective Tissue (...) fills the spaces between cells and surrounds connective tissue fibers. It is clear, colorless, and viscous.
Ground substance
133
# Connective Tissue (...) connective tissues are the **"packing materials"** of the body. They fill spaces between organs, and **support epithelia**. These tissues **surround and support blood vessels, nerves, store lipids, and provide routes for diffusion of materials**.
Loose connective tissues
134
# Connective Tissue What are the three types of **loose connective tissue**?
1. Reticular connective tissue 2. Areolar connective tissue 3. Adipose connective tissue
135
# Connective Tissue **Identify the connective tissue:** **Function:** Cushions organs; provides support but permits independent movement; phagocytic cells provide defense against pathogens.
Areolar tissue
136
# Connective Tissue Where is **areolar** tissue located? | (hint: 4)
1. Within and deep to the dermis of the skin. 2. Covered by the epithelial lining of the digestive, respiratory, and urinary tracts. 3. Between muscles and around joints. 4. Around blood vessels and nerves.
137
# Connective Tissue **Identify the connective tissue** **Function:** Provides padding and cushions shock, insulates (reduces heat loss) and stores energy.
Adipose tissue
