Name and point to the ten muscles in the arm

Deltoids (anterior and middle) Deltoid posterior


Other muscle characteristics?.

1. Tone. A small number of of fibres in most muscles are contracted continuously. They do this to maintain posture, and thereby enable a limb to resist being passively stretched or elongated. This slight persistent contraction is called muscle tone. Muscle tone is increased by regular exercise: well toned muscles are firm and slightly springy to touch. This is because more fibres are continuously contracted. Individual variations. Different muscles of the body, and the same muscles, but on different individuals, vary in the degree of force, speed and endurance they are able to produce. All three characteristics will also vary in a particular muscle at different times. - . The muscles of children develop as they grow up - The muscles of people who neglect exercise will become less fit - in all senses of the word


Tell me about the relationship between agnoist and antagonist.

The agonist muscle is the one primarily responsible for the movement that is going to happen. It is their contraction that is directly responsible for the movement.

It follows that the antagonist, therefor is the muscle that would directly oppost that movement, should it contract. 

To allow free movement of the agonist muscle, the antagonist muscle must relax and lengthen

Muscles often come in agonist and antagonistic groups, these are called reciprocal innervation. They don't have to be the obvious ones e.g. bicep and tricep, it could be bicep and anterior deltoid



What is a synergist muscle?


A synergist is a muscle that contracts by makign the actions of the agonist stronger.


An example of this is when you flex at the elbow, the bicep is the agonist and the brachialis is the synergist.


What is this and what does it do?

It's the mastoid muscle, its insertion is at the temperal bone, behind the ear,, the orgin is between the clavical and sternum.


These two turn and nod the head.


What are these?

What do they do?

Where do they originate?

Where do they insert?

Why are they called what they're called?

Serratus anterior - serratus as they are shaped like a saw (serrated), anterior as they are at the front.

They orinate on the ribs and insert on the scapula

They are used to draw the scapula forward, aka they protract the scapula



Can I identify the location and the function of the pelvic floor?


  1. Stop us peeing ourselves
  2. movement of the pelvis and legs
  3. Sexual function
  4. Stop your ogans from falling out
  5. Getting the circulation going between the trunk and the legs
