Encephalon is a term used in anatomy for the brain. It can be pronounced as "en-sef-uh-lon" with the phonetic transcription of /ɛnˈsɛfəlɒn/. The word is derived from Greek language as "enkephalos" means "in the head". The spelling can be a bit confusing because of the unusual letter combination of "ph" which is sounded as f. However, with the help of phonetic transcription, the correct pronunciation of encephalon can be easily identified.
Encephalon refers to the complex organ that serves as the center of the nervous system in most vertebrates. It is commonly known as the brain. The encephalon is composed of various interconnected structures and tissues, including the cerebrum, cerebellum, and brainstem. These structures enable the brain to regulate and coordinate bodily functions, as well as process sensory information from the environment.
The cerebrum, also known as the cerebral cortex, is the largest division of the encephalon. It is responsible for higher mental functions such as consciousness, thinking, perception, and memory. The cerebellum, located at the posterior part of the brain, plays a vital role in motor control, balance, and coordination. The brainstem, situated beneath the cerebrum and in front of the cerebellum, connects the brain to the spinal cord and controls vital functions like breathing, heart rate, and blood pressure.
The encephalon is protected by several layers, including the skull and the meninges, which are membranes that surround and cushion the brain. Additionally, the brain receives a constant supply of oxygen and nutrients from the bloodstream, facilitated by a network of blood vessels. The proper functioning of the encephalon is crucial for the overall functioning and well-being of an organism. Disruptions or diseases affecting the encephalon can lead to various neurological disorders and cognitive impairments.

The word "encephalon" has its roots in Greek. It is derived from the combination of two Greek words: "en" meaning "within" or "inside", and "kephalḗ" meaning "head". So, "encephalon" essentially means "within the head" or "inside the skull".
