"Muscle morphology" refers to the physical structure, form, and characteristics of muscles in the body. It describes how muscles look, their size, shape, and arrangement. Full definition
Together, these data demonstrate the altered muscle morphology specific to fast muscles from IL - 15Rα — KO mice, suggesting that IL - 15Rα has a role in regulating the plasticity of fast EDL muscles. (jci.org)
Over the past 30 years, increasing numbers of physical therapists have employed conventional grayscale brightness mode (B - mode) ultrasound imaging (USI) to assess components of muscle morphology (the form and structure of muscle) and morphometry (measurements of muscle form or size) as a means to speculate on muscle function in both research and clinical settings [7][8][9].
