How do the hyoid muscles change during the evolution of vertebrate classes?
Step by step
Solved in 2 steps
- What is the function of the hyoid arch muscles of fish tetrapods?Pharyngeal slits are which of the following? Question 24 options: a) Openings in the pharynx. In aquatic chordates they allow for exit of water that enters the mouth. b) Elongations of the posterior portion of the body. Use for locomotion in fish, or balance in some terrestrial vertebrates. c) Flexible, rod-shaped structures that grows from mesoderm. Gives support to an animal in embryonic development of chordates or for entire life depending on the species. d) Tissues that produces thyroid type hormones. e) Hollow tubes that develops from ectoderm. Develops into the central nervous system.How did the vertebrate appendage evolve into the limbs we find so useful today?
- How are mammalian gaits related to the molecular structure of muscle?What is the type of digestive system present in beings of the phylum Arthropoda? Are these animals protostomes or deuterostomes?What evolutionary adaption has enable Arthropods to be the most diverse group within the animal kingdom?
