Dorsal and ventral roots are a feature of spinal nerves only. Cranial nerves do not have dorsal and ventral roots.
The dorsal cavity consists of the cranial cavity (holds the brain) and the vertebral cavity (contains the spinal cord) and it is superior to the ventral cavity.
Ventral root is the ventral portion of spinal cord,there is no ganglion,cell body is of motor types ,cell info goes out of spinal cord of anterior horn. dorsal root is dorsal portion of spinal cord,it posses ganglion,cell body is of sensory types,information goes into spinal cord posterior horn
thoracic and abdominopelvic cavity
Central Nervous System?
for the nerves the peripheral nervous system, for your brain and spinal cord the cental nervous system.
spinal nerve
Spinal nerves (aka mixed spinal nerves) are formed from the dorsal and ventral roots coming out of the spinal cord.A spinal nerve is made of mixed nerves. They have both sensory and a motor aspect. The roots of sensory fibers are on the dorsal side of the spinal cord.

The ventral roots contains motor fibers, responsible for motion, whereas the dorsal sensory fibers, responsible for touch and feeling.
The dorsal cavity consists of the cranial cavity (holds the brain) and the vertebral cavity (contains the spinal cord) and it is superior to the ventral cavity.
cranial cavity, which contains the brain, and spinal cavity, formed by the vertebrae, which contains the spinal cord.
cranial which contains the brain and spinal which contains the nerves of the spinal cord.
multipolar neuron
Each spinal nerve attaches to spinal cord by a ventral (anterior) root and a dorsal (posterior) root.All spinal nerves are mixed nerves (both motor and sensory).
No. The spinal cavity is part of the Dorsal cavity, which also includes the cranial cavity. The spinal cavity is the space in vertebrae(spinal bones) through which the spinal cord passes.
The tips of the anterior horns are broader and less tapered than those of the posterior horns. Human Anatomy & Physiology Laboratory Manual Ninth Edition Elaine N. Marieb & Susan J. Mitchell
The cranial cavity contains the brain, pineal and hypophysis cerebri, parts of the cranial and spinal nerves, blood vessels, meninges and cerebrospinal fluid.
