There are four types of neurons: Sensory: Sensory neurons deliver electrical signals from the outer parts of the body — the glands, muscles, and skin — into the CNS. Motor: Motor neurons carry signals from the CNS to the outside parts of the body.

The function of motor neurons is to transmit signals from the brain and spinal cord to muscle cells. Thus, they are responsible for voluntary and involuntary movements of all our muscle cells. Motor neurons rapidly conduct electrical signals in order to cause these effects in our cells.

Answer:
a. Sensory neurons are nerve cells within the nervous system responsible for converting external stimuli from the organism's environment into internal electrical impulses. For example, some sensory neurons respond to tactile stimuli and can activate motor neurons in order to achieve muscle contraction.
b. cranium - or skull protects or inner brain from external injury. vertebral column-The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for the body and attachment for the pectoral and pelvic girdles and many muscles
d. Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.
