So the teres major muscle from its origin to the front of the humerus is all palpable? Like at what point on the scapula are you not palpating the muscle, is it right at the posterior axillary fold crease and same situation with the lat? I just don't understand how they end yp at the front of the humerus and the latissimus muscle actually becomes anterior to the teres major.

Honestly this is a very challenging question to answer through text. The origin and majority of its belly is easily palpable until it start to go into the axilla near triceps. Often teres major and lats are fascially attached to each other. They will become very challenging to palpate as the pass deep to the brachial plexus, coracobrachialis and biceps short head. At this point you are vaguely palpating it. Teres stays posterior to Lats as the go forward and therefore is on the medial lip of the bicipital groove vs lats going further into it. Please look up a picture of the two muscles inserting together and I suggest an anatomy app so you can see the brachial plexus and circulatory system near there insertion too.
