Coordination & Control - Solved MCQs with Explanations

Below are important MCQs from MDCAT Biology Chapter 5 (Coordination & Control). Each question includes the correct answer highlighted in green and a detailed explanation to help you understand the concept.

Q1 Easy Neurons

The basic unit of the nervous system is:

A Nephron
B Neuron
C Neutrophil
D Nucleotide
Explanation

Neurons are the fundamental units of the nervous system, specialized for transmitting electrical and chemical signals throughout the body.

Q2 Easy Synapses

Synapse is the junction between:

A Two bones
B Two neurons
C Two muscles
D Two arteries
Explanation

A synapse is the gap between two neurons where neurotransmitters carry signals from the presynaptic to the postsynaptic neuron.

Q3 Easy Brain Structure

Which part of the brain controls balance?

A Cerebrum
B Cerebellum
C Medulla
D Thalamus
Explanation

The cerebellum coordinates voluntary movements, balance, and posture. It receives input from sensory systems and the spinal cord.

Q4 Easy Endocrine System

Insulin is produced by:

A Alpha cells
B Beta cells of pancreas
C Thyroid gland
D Adrenal gland
Explanation

Beta cells of the Islets of Langerhans in the pancreas produce insulin, which lowers blood glucose levels by promoting glucose uptake.

Q5 Medium Synapses

The neurotransmitter at neuromuscular junction is:

A Dopamine
B Serotonin
C Acetylcholine
D GABA
Explanation

Acetylcholine is the neurotransmitter at the neuromuscular junction. It binds to receptors on muscle cells to trigger contraction.

Q6 Easy Nervous System

Fight or flight response is controlled by:

A Parasympathetic system
B Sympathetic nervous system
C Somatic system
D Central nervous system
Explanation

The sympathetic nervous system triggers the fight-or-flight response, increasing heart rate, dilating pupils, and releasing adrenaline.

Q7 Medium Neurons

Myelin sheath is produced by:

A Neurons
B Schwann cells
C Red blood cells
D Platelets
Explanation

Schwann cells produce the myelin sheath in the peripheral nervous system, insulating axons and increasing the speed of nerve impulse conduction.

Q8 Easy Hormones

Thyroid hormone controls:

A Blood sugar
B Metabolic rate
C Blood pressure
D Digestion only
Explanation

Thyroid hormones (T3 and T4) regulate the body's metabolic rate, affecting heart rate, body temperature, and energy usage.

Q9 Medium Neurons

The resting potential of a neuron is approximately:

A +70 mV
B -70 mV
C 0 mV
D -120 mV
Explanation

The resting membrane potential is about -70 mV, maintained by the sodium-potassium pump (3 Na+ out, 2 K+ in) creating a negative interior.

Q10 Medium Hormones

ADH hormone is produced by:

A Thyroid
B Hypothalamus
C Adrenal cortex
D Liver
Explanation

Antidiuretic hormone (ADH/vasopressin) is produced by the hypothalamus and stored/released by the posterior pituitary gland.
