Tissues and Membranes Lecture Notes

These flashcards cover key vocabulary terms and definitions related to tissues and membranes, facilitating a better understanding of their functions and characteristics.

What are the types of connective tissue?

The types of connective tissue include loose connective tissue, dense connective tissue, specialized connective tissue (like cartilage, bone, blood, and adipose tissue).

What is loose connective tissue?

Loose connective tissue serves as a filler between other tissues and contains a variety of cell types and fibers; it provides support and elasticity.

What is dense connective tissue?

Dense connective tissue is characterized by a high density of fibers and is divided into dense regular and dense irregular tissue, providing strength and stability.

What is regular dense connective tissue?

Regular dense connective tissue is characterized by tightly packed collagen fibers that run parallel to each other, providing strong tensile strength in one direction; it is found in tendons and ligaments.

What is the difference between hyaline cartilage and fibrocartilage?

Hyaline cartilage is smooth and glassy, reducing friction in joints, while fibrocartilage is tough and provides tensile strength, found in intervertebral discs.

What role does adipose tissue play in the body?

Adipose tissue stores energy in the form of fat, provides insulation, and serves as a protective cushion for organs.

What type of connective tissue forms the framework of organs?

Reticular connective tissue forms a supportive framework for organs such as the spleen, liver, and lymph nodes.

What is the extracellular matrix (ECM)?

The extracellular matrix is a network of proteins and carbohydrates located outside of cells, providing structural and biochemical support.

What are the classifications of connective tissue based on their structure?

Connective tissue can be classified into two main categories based on structure: loose connective tissue and dense connective tissue.

What are the functions of blood as connective tissue?

Blood functions as a transport medium for nutrients, gases, hormones, and waste products; it also plays a role in immune response.

What are the subgroups of dense connective tissue?

The subgroups of dense connective tissue include dense regular connective tissue, dense irregular connective tissue, and elastic connective tissue, each serving different functional roles in the body.

What is dense irregular connective tissue?

Dense irregular connective tissue has collagen fibers that are not arranged in a parallel fashion, allowing it to withstand tension from multiple directions; it is found in dermis of the skin and capsules around organs.

What is elastic connective tissue?

Elastic connective tissue contains a high density of elastic fibers, allowing it to stretch and return to its original shape, found in structures such as arteries and the lungs.
