Answer:
While skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles, called intercalated discs. Striated muscle contracts and relaxes in short, intense bursts, whereas smooth muscle sustains longer or even near-permanent contractions.
Passive transport:
For simple diffusion = fatty acids, amino acids, steroid hormones (because they’re non-polar)
Facilitated diffusion = N2 and Cl-
The study of comparative anatomy predates the modern study of evolution. Early evolutionary scientists like Buffon and Lamarck<span> used comparative anatomy to determine relationships between species. Organisms with similar structures, they argued, must have acquired these traits from a common ancestor. Today, comparative anatomy can serve as the first line of reasoning in determining the relatedness of species. However, there are many hidden dangers that make it necessary to support evidence from comparative anatomy with evidence from other fields of study.</span>
Answer:
Muscle fatigue is often reported by patients with Marfan syndrome although myopathy is not classically considered a component of Marfan syndrome [1, 2, 4, 6, 7]. In addition to apparent muscle underdevelopment, some patients report myalgia or cramps suggesting skeletal muscle involvement.
