Document Summary
Adaptations that led to the varying lengths of the laryngeal nerve in tetrapods can be illustrated with an analogy. The early embryos of fish and tetrapods are very similar. In their embryos, the laryngeal nerve connects the brain to a rudimentary structure that: In these embryos, the nerve hooks under the aorta: But in tetrapods, the aorta ends up in the chest, resulting in an elongated laryngeal. This is not problematic in fish because they do not have necks nerve in tetrapods. Tissues are an integrated group of similar cells that perform a common function. Animals consist of a hierarchy of levels of organization. Organs perform a specific task and consist of two or more tissues. Organ systems consist of multiple organs that perform a vital body function. Are an integrated group of similar cells that perform a common function. Animals have four main categories of tissues: epithelial tissue, connective tissue, muscle tissue, nervous tissue.
