Which type of tissue is responsible for contracting to produce movement in the body?
Muscle tissue
Connective tissue
Epithelial tissue
Nervous tissue
The Correct Answer is A
A. Muscle tissue: Muscle tissue is composed of cells (fibers) that have the unique ability to shorten or contract. This contraction generates the force required for body movement (skeletal muscle), pumping blood (cardiac muscle), and moving substances through hollow organs (smooth muscle).
B. Connective tissue: The primary function of connective tissue is to support, bind together, and protect tissues and organs (e.g., bone, cartilage, blood, and adipose tissue). It provides structure but does not generate active movement through contraction.
C. Epithelial tissue: Epithelial tissue forms the covering of all body surfaces, lines body cavities and hollow organs, and is the major tissue in glands. Its main functions are protection, secretion, absorption, and excretion.
D. Nervous tissue: Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities by transmitting electrical signals (impulses), not by physical contraction.

Correct Answer is D
Explanation
A. Thyroxine:Although thyroxine (T4) is regulated by a negative-feedback loop in the hypothalamic-pituitary-thyroid axis (TRH → TSH → T4/T3), its primary role is regulation of metabolism rather than direct, minute-to-minute control of blood glucose. It can influence glucose metabolism over time but is not the main hormone for acute blood glucose homeostasis.
B. Adrenaline:Adrenaline (epinephrine) increases blood glucose by stimulating glycogenolysis and gluconeogenesis during stress or “fight-or-flight.” Its release is driven largely by sympathetic nervous system activation (a feedforward/acute stress response), not by a classic negative-feedback loop aimed at maintaining steady blood glucose.
C. Oxytocin:Oxytocin is regulated by neural reflexes and some feedback mechanisms (notably positive feedback during labor), and it primarily influences uterine contraction and milk let-down. It is not involved in blood glucose regulation.
D. Insulin:Insulin is the primary hormone that reduces blood glucose and is tightly regulated by a negative-feedback mechanism: rising blood glucose stimulates insulin release from pancreatic β-cells; insulin lowers blood glucose (by promoting cellular uptake and storage), which then reduces the stimulus for further insulin secretion.
Correct Answer is D
Explanation
A. Autonomic nervous system: Controls involuntary functions such as heart rate, digestion, and temperature regulation. While autonomic neuropathy exists, peripheral neuropathy of extremities is not primarily autonomic.
B. Enteric nervous system: Controls GI tract functions. Not involved in neuropathy affecting limbs.
C. Central nervous system: Includes the brain and spinal cord. Peripheral neuropathy affects nerves outside the CNS.
D. Peripheral nervous system: Peripheral neuropathy is a disorder of the peripheral nerves that transmit sensory and motor signals to the limbs. Causes include diabetes, vitamin deficiencies, toxins, and trauma.
