Detailed explanation-1: -The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord. The spinal cord begins at the bottom of the brain stem (at the area called the medulla oblongata) and ends in the lower back, as it tapers to form a cone called the conus medullaris.
Detailed explanation-2: -The brainstem is the lower part of the brain that connects with the spinal cord.
Detailed explanation-3: -The central nervous system (CNS) is made up of the brain and spinal cord which is the nerve center of the body.
Detailed explanation-4: -The CNS is derived from the neuroectoderm: notochord induces the formation of the neural plate (thickening of the ectodermal layer), which further differentiates to form neural folds with a neural groove in between, leading to the formation of the neural tube (via neurulation).
Detailed explanation-5: -The central nervous system (CNS) is made up of the brain, cerebellum and the spinal cord. Nerves make up the peripheral nervous system (PNS), which works to send signals to and from the CNS, the body’s organs, muscles, and senses. More items •17-Aug-2020
