Animal Anatomy & Physiology - Chapter 5: Tissues

A set of flashcards to review key concepts, functions, and classifications of tissues as covered in the Animal Anatomy & Physiology lecture notes.

What are the four types of tissues in animals?

Epithelial, Connective, Muscle, Nervous.

What is the primary function of epithelial tissues?

To cover, protect, and line other tissues.

How are epithelial tissues classified?

By the number of layers (simple or stratified), shape of cells (squamous, cuboidal, columnar), and presence of surface specialization.

What is the role of the cell membrane?

Acts as a flexible barrier governing the movement of molecules in and out of the cell.

What is the nucleus often referred to as?

The brain or CEO of the cell.

What are the functions of epithelial tissues?

1. Protect, cover, and line; 2. Filter biochemical substances; 3. Absorb nutrients; 4. Provide sensory input; 5. Manufacture secretions; 6. Manufacture excretions.

What characterizes simple squamous epithelium?

It is thin, flat, and smooth, and is found in areas like the inner lining of lungs.

What is the function of connective tissue?

To provide support, structure, and nutritional support throughout the body.

What are the types of connective tissues mentioned?

Adipose, reticular connective, cartilage, bone, and blood.

What is the main characteristic of muscular tissues?

Designed for contraction to enable movement.

What are the three types of muscle tissues?

Skeletal, smooth, and cardiac.

What are the two types of cells found in nervous tissue?

Neurons and neuroglial cells.

What is granulation tissue?

New tissue that forms beneath a blood clot or scab during the healing process.

What are the steps of inflammation?

1. Vasodilation; 2. Swelling; 3. Clot formation; 4. Phagocytosis; 5. Capillary return.

What is 'proud flesh' in the context of wound healing?

Excess granulation tissue that forms during the healing process.
