List the muscles described in this lecture and describe their general attachments to the skeleton.
• Understand the relationship between muscle location, muscle contraction and joint movement.
• Determine the ‘concentric action’ of these muscles.
Which muscle has two origins on the scapula, 3 bodies, and one insertion to the humerus?
Respuesta
Biceps brachii
Biceps femoris
Deltoid
Triceps brachii
Pregunta 2
Pregunta

Respuesta
True
False
Pregunta 3
Pregunta
Choose the incorrect statement.
EXCLUDE the knee joint for this question!
Respuesta
A muscle placed anterior over a joint allows flexion.
A muscle placed posterior to a joint allows extension.
A muscle medial to the joint allows abduction.
