Question | Answer |
---|---|
What are the 2 structural divisions of the nervous system? | CNS (Central Nervous System) & PNS (Peripheral Nervous System) |
The part of the nervous system involved with structures of the limbs and body wall | SOMATIC |
The part of the nervous system involved with the visceral organs | VISCERAL |
The 2 components of the nervous system that bring information to the CNS | AFFERENT & SENSORY |
The 2 components of the nervous system that transmit information from the CNS | EFFERENT & MOTOR |
These fibers provide motor innervation to skeletal muscles of the body wall and limbs. | GSE (General Somatic Efferent) |
These fibers provide sensory information from the body wall and limbs such as pain, temperature, touch, vibration, and proprioception. | GSA (General Somatic Afferent) |
These fibers provide motor innervation to the smooth muscle, cardiac muscle, and glands. | GVE (General Visceral Efferent) |
GVE fibers are also referred to as the ___. | ANS (Autonomic Nervous System) |
The ANS is divided into these two classifications: | SYMPATHETIC AND PARASYMPATHETIC |
These fibers provide sensory information from the viscera such as pain or distension. | GVA (General Visceral Afferent) |
These nerves come off segmentally from the spinal cord in a paired manner (right and left). | SPINAL NERVES |
Each left and right spinal nerve divides again into ___ and ___ rami. | DORSAL/POSTERIOR & VENTRAL/ANTERIOR |
