Fibrous Connective Tissue

A type of connective tissue made up of mainly collagen that is strong and moderately stretchy

Makes up ligaments, tendons, and fasciae

Red Blood Cells

AKA erythrocytes

Most common type of cell in the body

Don't contain a nucleus ('anucleated'), providing more room for hemoglobin to transport oxygen or carbon dioxide to and from tissues and organs

Phagocytosis

'Cell eating' in Greek

The process by which a cell engulfs and digests pathogens and cellular debris in the body

A type of connective tissue found throughout the body that serves as an energy source and an organ and body cushion and insulator

Also known as fat

Two types: white and brown

Made of elastin

Are capable of stretching and contracting, like a rubber band

Flashcard Content Overview

Connective tissue is one of the four major types of tissue found in your body, and it is incredibly important. If connective tissue were a movie star, you might just expect to hear, 'And the award for best supporting actor goes to...connective tissue!' There are different types of connective tissue, and these flashcards will help you review what they are made of, where they are found, and what types of roles they perform for the body.

Connective Tissue

A tissue containing cells within an extracellular matrix that often support and give structure to the body or hold others tissues together

Types: bone, cartilage, fat, blood, loose, and fibrous

Loose Connective Tissue

Most common connective tissue in the body, made up of a loose connection of fibers such as collagen and elastic fibers

Connects, stabilizes, and structurally supports tissues and organs

Collagenous Fibers

Made of collagen

Act like glue to provide structural support to the body

Elastic Fibers

Made of elastin

Are capable of stretching and contracting, like a rubber band

Reticular Fibers

Made by reticular cells

Form a mesh to support the organs in the body

Adipose Tissue

A type of connective tissue found throughout the body that serves as an energy source and an organ and body cushion and insulator

Also known as fat

Two types: white and brown

Phagocytosis

'Cell eating' in Greek

Red Blood Cells

AKA erythrocytes

Most common type of cell in the body

Don't contain a nucleus ('anucleated'), providing more room for hemoglobin to transport oxygen or carbon dioxide to and from tissues and organs

Fibrous Connective Tissue

A type of connective tissue made up of mainly collagen that is strong and moderately stretchy

Makes up ligaments, tendons, and fasciae

Chondroblasts
Specialized cells that produce the extracellular matrix found in cartilage
Chondrocytes
The name given to chondroblasts found within the extracellular matrix of cartilage
Cartilage

A type of flexible but stable connective tissue that provides support for the body

Made up of an extracellular matrix filled with chondrocytes

Three types: elastic, hyaline, and fibrocartilage

Short Bone

A type of bone in which its length and width are approximately the same

Important for stabilizing the body and allowing small amounts of movement

Example: tarsals in ankle

Flat Bone

A type of bone that is flat

Protect the body and provide a muscle attachment surface

Example: the ribs

Irregular Bone

A type of bone that does not fit into any other category due to its odd shape

Example: vertebrae

Sesamoid Bone

A type of bone that is imbedded in a tendon

Important for protecting tendons and allowing for efficient joint movement

Example: patella (kneecap)

Hematopoiesis

The process by which red blood cells are made

Occurs in red bone marrow, which is found at the end of long bones and in flat bones

Number of Bones in the Human Body

Fetal skeleton: approximately 275 bones and a high percentage of cartilage

Adult skeleton: approximately 206 bones and a small percentage of cartilage

Difference due to bone fusion throughout aging

Fibroblasts
Cells found in the extracellular matrix of loose connective tissue responsible for secreting matrix proteins and aiding in wound repair, tissue remodeling, and tissue growth
