Flashcards Chapter 5-Tissues

These flashcards cover key concepts related to tissues as outlined in the lecture notes on Chapter 5.

What are the four major types of tissues in the body?

Epithelial tissue, Connective tissue, Muscle tissue, Nervous tissue

What is histology?

The study of tissues.

What are the general characteristics of epithelial tissues?

Cover organs and body surface, line cavities and hollow organs, make up glands, lack blood vessels (avascular), cells readily divide.

How are epithelial tissues classified?

According to cell shape (squamous, cuboidal, columnar) and number of layers (simple, stratified, pseudostratified).

What is the primary function of connective tissues?

Bind structures together, provide support and protection, fill spaces, store fat, produce blood cells.

What are the two main categories of connective tissue?

Connective Tissue Proper and Specialized Connective Tissues.

What is the difference between endocrine and exocrine glands?

Endocrine glands secrete into tissue fluid or blood, while exocrine glands secrete into ducts that open onto a surface.

What are the three types of muscle tissue?

Skeletal muscle, cardiac muscle, and smooth muscle.

What are the main components of nervous tissue?

Neurons and neuroglia.

What is the function of fibroblasts in connective tissue?

Secrete fibers into the extracellular matrix.

Where is simple squamous epithelium found?

In air sacs (alveoli) and capillaries.

What are the distinguishing characteristics of connective tissues?

Cells are farther apart than epithelial cells with abundant extracellular matrix in between.

What type of epithelium is found in the lining of the respiratory passageways?

Pseudostratified columnar epithelium.

What is the primary function of adipose tissue?

Store fat, cushion and insulate.

Where is hyaline cartilage typically found?

Ends of bones in joints, in the nose, and respiratory passages.

What distinguishes cardiac muscle tissue?

It is striated, involuntary, and has intercalated discs.

What role do neuroglia play in the nervous system?

Support and nourish neurons.

What are the two types of secretion in glandular epithelium?

Endocrine secretion (into blood) and exocrine secretion (into ducts).
