Which type of tissue conducts impulses to and from the brain?

1. Epithelial tissue

2. Muscle tissue

3. Nerve tissue

4. Connective tissue

The correct answer is: Nerve tissue

Nerve tissue is responsible for conducting impulses to and from the brain. This type of tissue is composed of neurons, which are specialized cells that transmit electrical signals throughout the body. These signals allow for communication between the brain, spinal cord, and the rest of the body, facilitating responses to stimuli and coordination of various bodily functions. Additionally, nerve tissue includes glial cells that support and protect the neurons, ensuring their proper function. Other tissue types do not serve this primary function. Epithelial tissue primarily covers and protects surfaces, both inside and outside the body, and is not involved in impulse conduction. Muscle tissue is responsible for movement and contraction but does not conduct electrical signals in the same way that nerve tissue does. Connective tissue provides support, binds other tissues together, and has various functions, but it also does not conduct impulses. Thus, nerve tissue is distinctly specialized for the conduction of impulses, making it the correct choice.
