MODULE 1: BASIC SCIENCES — ANATOMY & PHYSIOLOGY
,Nervous System (Questions 1–10)
1. • Which cranial nerve is of primary concern to the oral and maxillofacial surgeon when
performing oral surgery in the mouth under local anesthesia?
A) Facial nerve (VII)
B) Glossopharyngeal nerve (IX)
C) Hypoglossal nerve (XII)
D) Trigeminal nerve (V)
Rationale: The trigeminal nerve (CN V) provides sensory innervation to the face, oral cavity,
and teeth via its three divisions (ophthalmic, maxillary, mandibular). It is the primary nerve
anesthetized for dental and oral surgical procedures.
2. • The central nervous system (CNS) consists of which of the following structures?
A) Brain and peripheral nerves
B) Spinal cord and autonomic ganglia
C) Brain and spinal cord
D) Cerebrum and cerebellum
Rationale: The CNS is anatomically defined as the brain and spinal cord, which serve as the
overall control center of the body.
3. • Which of the following best describes the primary function of the cerebral cortex?
A) Coordination of motor movements only
B) Regulation of autonomic functions
C) Thought, learning, memory, consciousness, sensation, and initiation of muscle
movement
D) Relay of sensory information to the spinal cord
Rationale: The cerebral cortex is responsible for higher-order functions including thought,
learning, memory, consciousness, sensation (pain, heat), and voluntary muscle movement
initiation.
, 4. • What is the primary role of the cerebellum?
A) Control of heart rate and respiration
B) Processing visual information
C) Coordination center for sensory receptors and movement coordination
D) Production of cerebrospinal fluid
Rationale: The cerebellum serves as a coordinating center for sensory receptors (vision,
hearing) and movement coordination.
5. • The core of the brain functions primarily as a:
A) Center for conscious thought
B) Relay station between sensory inputs from the periphery and the cerebral cortex
C) Primary motor control center
D) Site of cerebrospinal fluid production
Rationale: The core of the brain (including the thalamus and brainstem) acts as a relay
station between peripheral sensory inputs and the cerebral cortex, and plays a key role in
autonomic functions and emotions.
6. • What is the fundamental functional unit of the nervous system?
A) Neuron
B) Glial cell
C) Axon
D) Synapse
Rationale: The neuron is the fundamental functional unit of the nervous system, responsible
for transmitting electrical and chemical signals.
7. • The peripheral nervous system (PNS) is subdivided into which two main divisions?
A) Central and peripheral
B) Motor and sensory
C) Somatic and autonomic
D) Cranial and spinal
