“…The migrating MMPs also carry the CXC chemokine receptor, CXCR4, and are attracted toward the limb mesenchyme, where the CXCR4 ligand (CXCL12; also known as SDF-1) is produced [ 185 ]. CXCL12/CXCR4 signaling is involved in the secondary intrusion of limb bud-dwelling MMPs into the body wall (i.e., the in-out mechanism) [ 186 – 188 ].…”

While skeletal evolution has been extensively studied, the evolution of limb muscles and brachial plexus has received less attention. In this review, we focus on the tempo and mode of evolution of forelimb muscles in the vertebrate history, and on the developmental mechanisms that have affected the evolution of their morphology. Tetrapod limb muscles develop from diffuse migrating cells derived from dermomyotomes, and the limb-innervating nerves lose their segmental patterns to form the brachial plexus distally. Despite such seemingly disorganized developmental processes, limb muscle homology has been highly conserved in tetrapod evolution, with the apparent exception of the mammalian diaphragm. The limb mesenchyme of lateral plate mesoderm likely plays a pivotal role in the subdivision of the myogenic cell population into individual muscles through the formation of interstitial muscle connective tissues. Interactions with tendons and motoneuron axons are involved in the early and late phases of limb muscle morphogenesis, respectively. The mechanism underlying the recurrent generation of limb muscle homology likely resides in these developmental processes, which should be studied from an evolutionary perspective in the future.

“…The embryological development of the pectoral muscles takes place in two stages [33]. During the first stage, myogenic cells migrate from the dermomyotome to the precursor of the upper limb, while, in the second stage, these cells return to the trunk, where they anchor the shoulder region to the body wall, forming the pectoral and latissimus dorsi muscles [42–44]. The final anatomic distribution of the pectoral muscles is the result of the three processes of migration, fusion, and apoptosis of the myogenic cells, and any alteration in these processes can modify the origin or insertion points of the muscles or produce supernumerary muscles [33].…”

“…The pectoralis major and pectoralis minor of Pan troglodytes , Pan paniscus , and Homo sapiens have different anatomic patterns with a high degree of variation that may be the result of their evolutionary history and embryological development [44]. The pectoralis major and the pectoralis minor have a species-specific anatomic pattern in common chimpanzees, bonobos, and humans.…”

We have analyzed anatomic variations in the pectoralis major and pectoralis minor muscles of common chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) and compared them to anatomic variations in these muscles in humans (Homo sapiens). We have macroscopically dissected these muscles in six adult Pan troglodytes, five Pan paniscus of ages ranging from fetus to adult, and five adult Homo sapiens. Although Pan troglodytes are thought to lack a separate pectoralis abdominis muscle, we have identified this muscle in three of the Pan troglodytes; none of the Pan paniscus, however, had this muscle. We have also found deep supernumerary fascicles in the pectoralis major of two Pan troglodytes and all five Pan paniscus. In all six Pan troglodytes, the pectoralis minor was inserted at the supraspinatus tendon, while, in Pan paniscus and Homo sapiens, it was inserted at the coracoid process of the scapula. Some of the anatomic features and variations of these muscles in common chimpanzees and bonobos are similar to those found in humans, therefore enhancing our knowledge of primate comparative anatomy and evolution and also shedding light on several clinical issues.

“…Morphological muscle development is an often neglected or vaguely described topic in embryology textbooks and articles (Schoenwolf et al 2009;Sadler, 2012;Deries & Thorsteinsdottir, 2016;Pu et al 2016). Based on our experience gained in creating the 3D Atlas of Human Embryology (de Bakker et al 2016), we hypothesized that human embryonic muscle anatomy is more advanced than would be concluded from descriptions in literature.…”

Hitherto unknown detailed muscle anatomy in an 8‐week‐old embryo

Congenital muscle diseases, such as myopathies or dystrophies, occur relatively frequently, with estimated incidences of up to 4.7 per 100 000 newborns. To diagnose congenital diseases in the early stages of pregnancy, and to interpret the results of increasingly advanced in utero imaging techniques, a profound knowledge of normal human morphological development of the locomotor system and the nervous system is necessary. Muscular development, however, is an often neglected topic or is only described in a general way in embryology textbooks and papers. To provide the required detailed and updated comprehensive picture of embryologic muscular anatomy, three‐dimensional (3D) reconstructions were created based on serial histological sections of a human embryo at Carnegie stage 23 (8 weeks of development, crown–rump length of 23.8 mm), using amira reconstruction software. Reconstructed muscles, tendons, bones and nerves were exported in a 3D‐PDF file to permit interactive viewing. Almost all adult skeletal muscles of the trunk and limbs could be individually identified in their relative adult position. The pectoralis major muscle was divided in three separate muscle heads. The reconstructions showed remarkable highly developed extraocular, infrahyoid and suprahyoid muscles at this age but surprisingly also absence of the facial muscles that have been described to be present at this stage of development. The overall stage of muscle development suggests heterochrony of skeletal muscle development. Several individual muscle groups were found to be developed earlier and in more detail than described in current literature.
