GENERAL HISTOLOGY

Detailed explanation-1: -At low magnificaiton, skeletal muscle in longitudinal section is non-branching and can be identified by peripheral nuclei.

Detailed explanation-2: -Human skeletal muscles are composed of three major fiber types, slow type 1, fast 2A, and fast 2X fibers, defined by the presence of MYH7 (myosin heavy chain 7), MYH2, and MYH1, respectively, as well as hybrid fibers containing multiple MYHs, most frequently MYH7 + MYH2 (type 1–2A) or MYH2 + MYH1 (2A–2X) [1].
