Connective tissue

Material between the cells of the body that gives tissues form and strength

1

Collagen

The most abundant protein in the body

2

Collagen fibers major physical properties

Tensile strength and relative and extensibility

3

Fascicles

The wavy bundled arrangement of the collagen of a tendon

4

Collagen fibers maximum extension

3%

5

Elastic fibers

Made of amino acids and responsible for determining the possible range of extensibility of muscle cells; submit to fragmentation, fraying, and calcification due to the aging process

6

Elastic fibers extension

Succumb readily to stretching, and Whinerli's to return to their former length; rupture at approximately 150% of original length

8

Ligaments

Functions to support a joint by attaching bone to bone; pliant and flexible allowing freedom of movement but also inextensible so as not to yield easily to applied force

9

Fascia

All fibrous connective tissue not otherwise specifically named

10

Superficial fascia

Lies directly below the skin and generally contains a collection of fat

11

Deep fascia (intramuscular fascia)

Lies directly beneath the superficial fascia encasing muscles, bones, nerves, blood vessels, and organs

12

Subserous fascia

Forms the fibrous layer of membranes that cover and support the innermost body cavities

13

Deep fascia (intramuscular fascia) functions

To provide a framework that ensures proper alignment of muscle fibers blood vessels and nerves, enabled the safe and effective transmission of force throughout the whole muscle, and provide necessary lubricated surfaces between muscle fibers that allow muscles to change shape

14

Joint capsule (ligaments) contribution to flexibility

47%

15

Muscle (fascia) contribution to flexibility

41%

16

Tendons contribution to flexibility

10%

17

Skins contribution to flexibility

2%

18

Tendons

Tough cord like tissue that connects muscles to bone to produce motion
