Introduction to Anatomy - Primary Tissues

Flashcards based on the primary tissue types covered in the lecture, focusing on definitions, classifications, and functions.

What are the four primary tissue types of the body?

Muscle, Nervous, Connective, and Epithelial tissues.

Epithelia

A sheet of cells that covers a body surface or cavity and forms the covering and linings throughout the body.

Connective Tissue

Tissue that supports and binds together other tissues and organs; includes various types such as loose, dense, cartilage, and blood.

Types of Muscle Tissue

Skeletal muscle (voluntary), Cardiac muscle (involuntary), Smooth muscle (involuntary).

Nervous Tissue

Tissue that consists of neurons and neuroglia, responsible for transmitting electrical impulses and supporting nerve cells.

Simple Squamous Epithelium

Single layer of flat cells that facilitates diffusion and is involved in protection and filtration.

Extracellular Matrix (ECM)

A component of connective tissue made up of protein fibers and ground substance, crucial for tissue functions and properties.

Types of Cartilage

Hyaline cartilage, elastic cartilage, and fibrous cartilage, each with specific functions like flexibility, support, and shock absorption.

Cell Shapes in Epithelium

Squamous, Cuboidal, Columnar, and Transitional, which determine the function and location of epithelial tissues.

Functions of Connective Tissue

Support, protection, insulation, energy storage, and transportation.

Specialized Connective Tissue

Includes bone, cartilage, and blood; provides specific functions such as support, storage, and transport.

Keratin

A protein that provides waterproofing and protection in certain epithelial tissues.

Microvilli or Cilia

Surface specializations found in certain epithelial tissues that increase surface area or aid in movement.

Goblet Cells

Specialized epithelial cells that secrete mucus to lubricate surfaces and protect against pathogens.
