Building upon hypotheses of muscle homology recently published by our group and osteological correlates from the literature, we used extant phylogenetic bracketing and character optimization to reconstruct pectoral appendicular muscles in fossil taxa spanning the fin‐limb and water‐land transitions: the ...
Absence of the breast (also called amastia) frequently does not occur as the only physical problem. Unilateral amastia (amastia just on one side) is often associated with absence of the pectoral muscles (the muscles of the front of the chest). Bilateral amastia (with absence of both breast...
Catch yourself on the way down with bent elbows, about halfway into the next rep so that you absorb the reactionary forces with your muscles instead of your joints and tendons. Slow yourself down and reset before the next rep to train your smaller stabilizing muscles to engage and decelerate ...
The tendon spreads superolaterally into a muscle belly that inserts into the lower surface of the middle third of the body of clavicle (groove for subclavius muscle). The subclavius is enclosed by the clavipectoral fascia, which is a fibrous connective tissue that spans the interval between...
What is the function of cilia in the trachea? What are the functions of the skeletal-muscle system? What are the advantages of an endoskeleton? What is the role of calcium in integumentary system? What is the function of the pectoral girdle?

Structure and function of fish muscles 来自 ResearchGate 喜欢 0 阅读量: 73 作者: IA Johnston 摘要: Emphasis is on the highly endemic sub-order Notothenioidei. Adult stages of most species swim at low speeds using large pectoral fins (labriform locomotion). This is supplemented with sub-...
Intrinsic Muscles of the Back & Neck Muscles of the Abdomen The muscles of the abdomen can be separated into four pairs that cover the entire lateral and anterior part of the torso. The deepest muscles of the abdominal cavity are called thetransverse abdominis. Theserratus anteriorsits between...

Additionally, in the pectoral muscles of bats (Rhinolophus ferrumequinum Nippon), mitochondria-moderate fibers have well-development JFs [53]. In the white fibers of bottle-nose dolphins, marked branching of JFs also extended deep into the sarcoplasm [54]. Interestingly, even in cultured muscle ...
