Attachment site

Tendons are connected to a bone, this part of the bone is called an attachement site

Tendon

Tendons connect a muscle to a bone. Tendons are unable to contract.

They are a tough type of connetive tissue

Muscle

Muscles contract: This makes them shorter and thicker.

Or relax: This makes them longer and thinner

Most muscles contain a lot of cells that have multiple nuclei in them

Antagonistic pairs

Muscles can only pull, not push.

Often, muscles work together when moving bones.

Muscle 1 contracts, 2 relaxes

Muscle 2 contracts, 1 relaxes

These muscles are an:

 antagonistic pair

Voluntary and involuntary movements

Skeletal muscles 

• Move voluntary (when you want them to)
• Strong, but tires quickly
• Legs, arms, neck, back, etc.

Smooth muscles

• Move involuntary (on their own, without you controlling it) 
• Not as strong, but doesn't tire 
• In organs: oesophagus, skin, stomach, etc.

Cardiac muscles 

• move involuntary
• Strong, never tires
• in your heart

skeletal muscle contains cells that have multiple nuclei.

It is structured in neat striped rows

smooth muscle contains cells that have a nucleus. (like most cells)

It has many thin elongated (spindle-shaped) cells together

cardiac muscle contains cells that have a nucleus. (like most cells)

It's structure is a mix of skeletal and smooth muscle
