Major Brain Structures and Their Roles
Corpus Callosum
The bridge between the cerebral hemispheres is the corpus callosum.
Thalamus
Thalamus: Regulates communication between parts of the brain and relays sensory information; it also influences endocrine function.
Central Nervous System (CNS)
CNS: Consists of the brain and the spinal cord, covered by two protective layers (meninges).
Peripheral Nervous System (PNS)
PNS: The network of nerves that connects sensory receptors and effectors to the CNS; it links peripheral neurons to the central system.
Hippocampus
Hippocampus: Part of the limbic system important for long-term memory formation.
Hypothalamus
Hypothalamus: A primary regulator that connects nervous system activity to the endocrine system and helps
