04_Functional Anatomy

Functional anatomy classifies muscles according to:

• size

• shape

• action/motion

• all of the listed

What biarticulate muscle flexes the knee and plantarflexes the ankle?

• gastrocnemius

• soleus

• tibialis posterior

• tibialis anterior

What technique is used to identify when and how active a skeletal muscle is?

• functional anatomy

• electrocardiogram

• electromyography

• electroencephalogram

_________ is the simultaneous activation of many muscles to create a specific force or action.

• agonist

• antagonist

• synergy

• electromyography

For biomechanics, we assume the body is composed of rigid segments. This is an example of:

• modeling

• simulation

• inverse dynamics

• temporal-spatial parameters

Consider sagittal plane motion of a squat. During the downward phase, the motion at the knee is​ (a)   , the motion is produced by (b)   , the muscle action is ​ (c)   , and the active muscle group is the​ (d)   .

• flexion
• extension
• gravity
• muscles
• eccentric
• isometric
• concentric
• knee extensors
• knee flexors
