The nurse is preparing material about impulse transmission to help with a presentation on the neurological system. When discussing spinal nerves, the nurse will include that each spinal nerve is made up of the dorsal root and which other root?
- A. Medial
- B. Lateral
- C. Ventral
- D. Proximal
Correct Answer: C
Rationale: Each spinal nerve has two roots: the dorsal root, which carries sensory impulses into the spinal cord, and the ventral root, which carries motor impulses away from the spinal cord. The medial, lateral, and proximal roots are not part of the spinal nerve structure. Understanding this anatomy is essential for explaining how sensory and motor functions are integrated.
Regarding the circle of Willis
- A. Posterior cerebral is a branch of the internal carotid
- B. Anterior cerebral is the largest branch of the internal carotid
- C. Middle cerebral supplies motor but not sensory cortex
- D. Internal carotid gives off ophthalmic artery
Correct Answer: D
Rationale: The internal carotid artery gives off the ophthalmic artery, which supplies the eye and orbit. The circle of Willis provides collateral circulation to the brain.
Which of the following animals is NOT a typical reservoir for the spread of rabies?
- A. dog
- B. bat
- C. skunk
- D. chicken
Correct Answer: D
Rationale: The correct answer is D: chicken. Chickens are not typical reservoirs for rabies as they are not known to carry the rabies virus. Dogs, bats, and skunks can serve as reservoirs for rabies due to their susceptibility to the virus. Dogs are a common source of rabies transmission to humans, while bats and skunks are known carriers of the virus. Therefore, the correct answer is D as chickens do not play a role in the spread of rabies.
