ANATOMY

Detailed explanation-1: -Cerebrospinal fluid (CSF) leak occurs when there is a tear or hole in the membranes surrounding the brain or spinal cord, allowing the clear fluid that surrounds and cushions those organs to escape.

Detailed explanation-2: -Motor or efferent neurons transmit impulses from the central nervous system towards the effectors (muscle or glands), while sensory neurons transmit impulses from the sense organs towards the central nervous system (brain and spinal cord).

Detailed explanation-3: -The somatic nervous system consists of both afferent (sensory) and efferent (motor) nerves [1]. It is also responsible for the reflex arc, which involves the use of interneurons to perform reflexive actions. Besides these, there are thousands of other association nerves in the body.

Detailed explanation-4: -The autonomic nervous system controls all “automatic” body functions, such as breathing, heart rate, blood pressure, sweating, mouth-watering (salivating), and the movement of food through the intestines (peristalsis).
