Neurobiology, Theoretical Foundations & Therapeutic Relationships | Q&A |
Grade A | 100% Correct (Verified Answers)
Subject: Mental Health Nursing / Psychiatric-Mental Health
Source: NSG 221 Exam #1 – Comprehensive Review
Format: Q&A Guide with Clinical Rationale
1: What are neurotransmitters?
Correct Answer: Chemical substances manufactured in the neuron that aid in the transmission of
information throughout the body.
1. Neurotransmitters play a major role in everyday life and functioning.
2. Three actions: excitatory, inhibitory, and modulatory.
3. Categorized into six types: amino acids, peptides, monoamines, purines, gasotransmitters,
acetylcholine.
2: What does the central nervous system (CNS) consist of?
Correct Answer: Cerebrum, cerebellum, brain stem, and limbic system.
1. Cerebrum is divided into two hemispheres and four lobes.
2. Cerebellum coordinates movement and postural adjustments.
3. Brain stem contains vital centers for respiration and cardiovascular function.
3: What are the functions of the frontal lobe?
Correct Answer: Organization of thought, body movement, memories, emotions, and moral behavior.
1. Executive functions including planning and decision-making.
2. Broca's area for speech production located in left frontal lobe.
3. Personality and impulse control.
4: What are the functions of the parietal lobe?
Correct Answer: Sensations of taste and touch.
1. Processes sensory information from the body.
2. Spatial awareness and navigation.
3. Perception of pain and temperature.
, 5: What are the functions of the temporal lobe?
Correct Answer: Senses of smell and hearing.
1. Contains primary auditory cortex.
2. Wernicke's area for language comprehension.
3. Memory formation (hippocampus).
6: What are the functions of the occipital lobe?
Correct Answer: Coordinating language generation and visual interpretation.
1. Primary visual cortex.
2. Visual processing and recognition.
3. Depth perception and color identification.
7: What is the function of the cerebellum?
Correct Answer: Located below the cerebrum and is the center for coordination of movements and
postural adjustments. Inhibited transmission of dopamine in this area is associated with lack of smooth
coordinated movements in diseases such as Parkinson's disease and dementia.
1. Fine motor control and balance.
2. Motor learning and coordination.
3. Posture and gait regulation.
8: What is the function of the medulla?
Correct Answer: Located at the top of the spinal cord, contains vital centers for respiration and
cardiovascular functions.
1. Controls breathing, heart rate, and blood pressure.
2. Contains reflex centers for coughing, sneezing, swallowing.
3. Damage can be fatal.
9: What is the function of the pons?
Correct Answer: Above the medulla and in front of the cerebrum, it bridges the gap both structurally
and functionally, serving as a primary motor pathway.
1. Relays signals between cerebrum and cerebellum.
2. Involved in sleep regulation and arousal.
3. Contains cranial nerve nuclei.
10: What is the function of the midbrain?
Correct Answer: Connects the pons and cerebellum with the cerebrum; includes most of the reticular
activating system and the extrapyramidal system. The reticular activating system influences motor
activity, sleep, consciousness, and awareness.
1. Visual and auditory reflex centers.
2. Regulates consciousness and arousal.
3. Motor movement coordination.
