Tissues - Chapter 5 - Animal Anatomy & Physiology

Practice flashcards summarizing key concepts about tissues from Chapter 5 of Animal Anatomy & Physiology.

What are the four types of tissues in the body?

Epithelial, connective, muscle, and nervous tissues.

What is the primary function of epithelial tissues?

To cover and line surfaces of organs and cavities.

How are epithelial tissues classified?

Based on the number of layers (simple or stratified) and the shape of the cells (squamous, cuboidal, columnar).

What is the main characteristic of connective tissue?

It provides support, structure, and nutritional support to the body.

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 is the function of muscle tissues?

Muscle tissues are designed for contraction, enabling movement.

What are the three types of muscle tissues?

Skeletal, smooth, and cardiac muscle tissues.

What characterizes the structure of smooth muscle?

Smooth muscle has no striations, small cells with one nucleus, and is involuntary.

Where is cardiac muscle located and what is its unique characteristic?

Cardiac muscle is found in the heart and has striations; it is also involuntary.

What are the two main types of nervous cells?

Neurons and neuroglial cells.

What happens during the initial response to injury?

Inflammation occurs, which limits further damage and eliminates harmful agents.

What is granulation tissue?

A bright pink tissue that forms beneath a blood clot or scab, composed of collagen fibers and capillaries.

What is proud flesh?

Too much granulation tissue formed during healing.

What distinguishes endocrine glands from exocrine glands?

Endocrine glands lack ducts and secrete hormones into the bloodstream, while exocrine glands have ducts and release secretions locally.
