What do you think the difference is between ligaments and tendons?

​Tendons

Subject | Subject

Some text here about the topic of discussion

• ​ Connects muscle to bone

• Transfer tension created by the muscle to the bone to create movement.

• Mainly made up of the protein collagen. ​

​Collagen

Subject | Subject

Some text here about the topic of discussion

• ​ Inelastic tissue

• Great tensile strength​

• Most abundant protein in the body

• Structural component of all living tissue

​Ligaments

Subject | Subject

Some text here about the topic of discussion

• ​Connect bone to bone

• Provides support to the joint

• Composition similar to tendons, with collagen bundles located parallel to one another.

• Also contains a concentration of the protein elastin.​

​Elastin

Subject | Subject

Some text here about the topic of discussion

• ​Allows the ligaments some extensibility to return to the original length once a stretch or force is removed.

• This allows for a balance of support and resilience to the joint.​

​Sprains

​Strains

Strain vs Sprain

Some text here about the topic of discussion

• ​Affect tendons and muscles.

• sTrain (think "T" for tendons)​

• ​ Affect only ligaments

​ Neither one is any worse than the other, both are measured by severity. (Mild, severe, grade 1,2,3 etc.)

​Fascia

Subject | Subject

Some text here about the topic of discussion

• ​Latin word that means "bandage"

• Broad term to describe all connective tissue that does not have a specific name.

• Three types of Fascia, superficial fascia, deep fascia, and subserous fascia.​

​Superficial Fascia

Subject | Subject

Some text here about the topic of discussion

• ​Outermost fascia

• Lies directly below the skin

• Contains various amounts of fat within it. ​

​Deep Fascia

Subject | Subject

Some text here about the topic of discussion

• ​ Directly beneath superficial fascia

• Much more compact and tough.

• Fuses with muscle and bones.

• Also separates internal organs from each other​.

​Main Functions of Fascia

Subject | Subject

Some text here about the topic of discussion

1. ​Provides the intramuscular framework that binds muscle, safeguarding its stability.

2. Permits forces developed by the muscle to be transmitted securely and efficiently.

3. Offers a necessary insulation ​between various organs and tissues in the body.

Multiple Choice

Which layer of Fascia contains various amount of fat in it?

• Superficial Fascia

• Deep Fascia

Multiple Choice

Which layer of fascia fuses with muscle and bone, and separates internal organs?

• Deep Fascia

• Superficial Fascia

Multiple Choice

Which of these is not a main function of fascia?

• Binds the muscle, maintaining it's stability

• Allows the muscle to transmit forces securely and efficiently

• Offers insulation between organs and tissues in the body

• All of these are functions of fascia
