Anatomy Vocab

Front 1

Collagen Fibers

Back 1

connective tissue fiber; long, straight, and unbranched. most common- strong & flexible, result force in 1 direction EX: tendons & ligaments

Front 2

Reticular Fibers

Back 2

connective tissue fiber; network of interwoven fibers (Stroma); long & flexible- resist in many directions- stabilized functional cells (Parenchyma) & structures EX: Sheaths of Organs

Front 3

Elastic Fibers

Back 3

connective tissue fiber; contain elastin. Branched & wavy- return to original length after stretching EX: elastic ligaments of vertebrae

Front 4

Ground Substance

Back 4

fills space between cells and surrounds connective tissue fibers. clear, colorless, viscous. Dense enough that bacteria have trouble moving through it (slows speed of pathogens)

Front 5

Mesenchyme

Back 5

embryotic connective tissue; first connective tissue to appear in a developing embryo.

Front 6

Mucous Connective Tissues

Back 6

loose embryotic tissue; found in many parts of the embryo , including the umbilical cord.

Front 7

Loose Connective Tissues

Back 7

"Packing Materials" of the body.
Three Types in Adults: Areolar, Adipose, Reticular

Front 8

Areolar Tissue

Back 8

Loose Connective Tissue; least specialized; open framework; viscous ground substance.

Front 9

Adipose Tissue

Back 9

Loose Connective Tissue; contains adipocytes (Fat Cells) - white and brown

Front 10

White Fat

Back 10

most common, stores fat, absorbs shocks, slows heat loss (insulation)

Front 11

Brown Fat

Back 11

more vascularized, adipocytes have many mitochondria, when stimulated by nervous system; fat break down accelerates, releasing energy. Absorbs Energy from surrounding tissues

Front 12

Adipocytes

Back 12

do not divide in adults; expand to store fat, shrink as fats are released

Front 13

Mesenchymal

Back 13

cells divide and differentiate, produce more fat cells when storage is needed

Front 14

Adipose Tissue

Back 14

Location: Deep in the skin, especially at sides, buttocks, breasts; padding around eyes and kidneys
Function: Provides padding and cushions shocks; insulates (reduces heat loss); stores energy

Front 15

Reticular Tissue

Back 15

Location: liver, kidney, spleen, lymph nodes, & bone marrow
Function: provides supporting framework

Front 16

Dense Regular Connective Tissue

Back 16

Location: between skeletal muscles and skeleton (tendons); between bones or stabilizing positions of internal organs (ligaments); covering skeletal muscles; deep fasciae
Function: provides firm attachment, conducts pull of muscles, reduces friction between muscles; stabilize relative positions of bones

Front 17

Dense Irregular Connective Tissue

Back 17

Location: capsules of visceral organs; periostea and perichondria; nerve and muscle sheaths; dermis
Function: Provides strength to resist forces applied from many directions; helps prevent over-expansion of organs such as the urinary bladder

Front 18

Elastic Tissue

Back 18

Location: between vertebrae of the spinal column (ligamentum flavum & ligamentum nuchae) ligaments supporting penis, ligaments supporting transitional epithelia; in blood vessel walls
Function: stabilizes positions of the vertebrae and penis; cushions shocks; permits expansions and contraction of organs

Front 19

Capsule

Back 19

thick fibrous layer formed by the dense connective tissue
