CNS primary function

Exclusions from vertebrate CNS

True Brain Animals

Animals with a true brain include vertebrates such as mammals, birds, reptiles, amphibians, and fish.
Cephalopods like octopuses and squids also possess a complex brain structure.

Primary Function of the Central Nervous System (CNS)

The CNS coordinates and processes sensory information, controls voluntary and involuntary responses, and regulates bodily functions.

Composition of the CNS

The CNS is primarily composed of the brain and the spinal cord.
It is made up of neurons, glial cells, and blood vessels, facilitating communication and support.

Animals Excluded from Discussion of Vertebrate CNS

Invertebrates like arthropods, annelids, and cnidarians are typically excluded from discussions of the vertebrate CNS due to their simpler nervous systems.

Role of Meninges

Meninges are protective membranes that encase the brain and spinal cord.
They help to cushion the CNS, provide structural support, and contain cerebrospinal fluid that nourishes and protects neural tissues.
