Scapulohumeral rhythm exposes the function of the glenohumeral joint by testing at which degree the scapula activates during an initial abduction of the arm. At 45 degrees, the scapula should engage until the end range motion of abduction.

Totally agree with A being phasic!

Wait, are gastrocnemius and soleus really phasic?

C is not phasic, right?

I thought temporalis and masseter were phasic too?

A is definitely phasic!

I’m confused about the quadratus lumborum; I thought it was more stabilizing than phasic.

I practiced a question like this before, and I feel like the gastrocnemius and soleus are more tonic muscles, right?

I remember something about the temporalis and masseter being more postural, but I'm not entirely sure.

I think phasic muscles are more about movement, so maybe A with the triceps and deltoid?

Okay, I think I've got this. Phasic muscles are the ones that are more involved in dynamic movements, rather than postural support. So I'm going to go with option A - Triceps brachii and deltoid.

Hmm, I'm a bit confused on this one. I know phasic muscles are different from tonic muscles, but I can't remember the exact definition. I'll have to think this through carefully.

I'm pretty sure phasic muscles are the ones that contract and relax quickly, so I'm going to go with option C - Quadratus lumborum and cervical erector spinae.

I'm feeling pretty confident about this one. Phasic muscles are the ones that fatigue more quickly, so they're usually associated with limb movements. I'm going to select option D - Gastrocnemius and soleus.

This one seems pretty straightforward. The definition is talking about the probability of the system meeting performance standards, so I'm going to go with Reliability.

I can kind of recall something about routing and load balancing, but did we cover whether it directly relates to access for redundantly deployed services?

I bet the person who wrote this question has a really 'muscular' sense of humor. Puns and all.

C) Quadratus lumborum and cervical erector spinae, no doubt. That's the only option that makes sense for phasic muscles.

Yes, those muscles are responsible for more dynamic movements.

Hmm, this one's tricky. I'm leaning towards D) Gastrocnemius and soleus, but I could be totally off. I guess I need to brush up on my muscle groupings.

B) Temporalis and masseter? Really? Those are postural muscles, not phasic. I'm pretty sure the answer is C.
VE

I'm not sure, but I think C) Quadratus lumborum, cervical erector spinae are also phasic muscles because they are used for stabilization.

I think the correct answer is C) Quadratus lumborum, cervical erector spinae. Phasic muscles are typically involved in dynamic movements, and those muscle groups fit the bill.
