Some organisms, like sea sponges, lack a true nervous system. Others, like jellyfish, lack a true brain and instead have a system of separate but connected nerve cells (neurons) called a “nerve net.” Echinoderms such as sea stars have nerve cells that are bundled into fibers called nerves.

The CNS consists of the brain and spinal cord. The peripheral nervous system is an extensive network of nerves connecting the CNS to the muscles and sensory structures.

Key hormones include TRH, GnRH, GHRH, CRH, somatostatin, and dopamine, which influence the anterior pituitary's functions. TRH stimulates TSH and prolactin, GnRH is essential for reproduction, GHRH prompts growth hormone, and CRH causes ACTH release. Somatostatin and dopamine inhibit growth hormone and prolactin, respectively.

Actin filaments enhance mechanical strength and assist in muscle contraction and cytokinesis. Intermediate filaments, such as keratins, provide structural stability. Microtubules, the largest fibers, aid in intracellular transport and chromosome movements during division, and form structures like cilia and flagella.
