1

What is the delto-pectoral groove?

Triangle bounded by the clavicle superiorly, the deltoid laterally and the pectorals major medially

2

How do you examine the function of the sternocleidomastoid muscles?

Turn head to right or left against resistance (accessory nerve)

3

How do you examine the function of the trapezius muscle?

Raise both shoulders against resistance

How do you examine the function of the pectoralis major muscle?

Adduct the abducted arm against resistance (nerves- lateral and medial pectoral C5,6,7,8 and T1
