    Organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals

    The brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It consists of nervous tissue and is typically located in the head, usually near organs for special senses such as vision, hearing and olfaction. Being the most specialized organ, it is responsible for receiving information from the sensory nervous system, processing those information and the coordination of motor control. While invertebrate brains arise from paired segmental ganglia of the ventral nerve cord, vertebrate brains develop axially from the midline dorsal nerve cord as a vesicular enlargement at the rostral end of the neural tube, with centralized control over all body segments. All vertebrate brains can be embryonically divided into three parts: the forebrain, midbrain and hindbrain. Wikipedia

    Jan 25, 2025Your brain's job is to send, receive and process signals sent through your central nervous system. These signals are messages that carry information from your five senses (sight, smell, sound, touch and taste). Your brain also identifies signals from inside of your body, like pain, temperature or how fast your heart is beating. ...

The average size of the adult human brain is about 15 centimeters (6 inches) in length, 14 centimeters (5.5 inches) in width, and 9 centimeters (3.5 inches) in height. How fast do brain signals travel? Brain signal speeds vary depending on the type of neuron and the nature of the signal.
