Fig. 8. Connection of feather follicles with muscles.

Fig. 8

(A) The exquisite muscle connections of mature feather follicles (from Lucas and Stettenheim, 1972). (B-D) During development, the interbud mesenchyma are at first homogenous (E10), but gradually form specifically arranged muscle and tendon fibers which link feather follicles (E18).
