What type of tissue primarily composes the brain?

Nervous tissue
Epithelial tissue
Connective tissue
Muscle tissue

The correct answer is: Nervous tissue

The brain is predominantly composed of nervous tissue, which is essential for its function of processing and transmitting information throughout the body. Nervous tissue consists of neurons and supporting cells known as glial cells. Neurons are responsible for sending and receiving signals, while glial cells provide support, protection, and nourishment to neurons. This unique composition is crucial for the brain's ability to perform complex tasks such as cognition, sensory perception, and motor control. In contrast, the other tissue types—epithelial, connective, and muscle—serve different roles in the body. Epithelial tissue mainly covers and protects surfaces and cavities, connective tissue supports and binds different body parts, and muscle tissue is responsible for movement. Understanding the specific role of nervous tissue helps in grasping the overall function of the brain within the central nervous system.
