Practise 33 real Federal Board questions on Coordination and Control from 2023 to 2026. See the answer and explanation as soon as you answer.
Coordination and Control is one of the 15 main chapters in our Federal Board Matric Biology question bank (9th and 10th class), and about 8% of its real questions come from it. Tayyari Karo has 33 real questions on this chapter from 2023 to 2026; 10 are multiple choice and marked instantly, and the rest are short and long questions with a model answer. By difficulty: 23 medium, 10 easy.
Work through the questions below, then open the explanation for each one. Redo the ones you missed a few days later.
These are real past-paper questions. Think of your answer first, then open the explanation.
The central nervous system consists of:
Answer: B. Brain and spinal cord
The central nervous system (CNS) consists of the brain and spinal cord; nerves form the peripheral nervous system.
The thyroxine is produced by ________ gland.
Answer: A. Thyroid
Thyroxine is produced and secreted by the thyroid gland.
Fovea, a small depression in retina, is called:
Answer: B. Yellow spot
The fovea (yellow spot) is the region of the retina with the sharpest, most detailed vision.
Interneurons are only present in:
Answer: C. Brain and spinal cord
Interneurons (relay neurons) are found only within the central nervous system — brain and spinal cord.
Islets of Langerhans are part of the:
Answer: B. Pancreas
Islets of Langerhans are clusters of hormone-secreting cells (insulin, glucagon) within the pancreas.
Identify the part of hind brain which controls equilibrium and muscle coordination during riding a bicycle.
Answer: C. Cerebellum
The cerebellum maintains balance, posture and coordinates fine muscular movement.
Briefly describe three types of neurons.
(1) Sensory (afferent) neurons — carry nerve impulses from receptors towards the central nervous system (brain/spinal cord). (2) Motor (efferent) neurons — carry nerve impulses from the central nervous system to effectors (muscles/glands). (3) Relay (inter) neurons — found within the central nervous system, connecting sensory and motor neurons and processing/coordinating information.
Perform a comparison between eye and ear as sensory receptors. (Any three points)
(1) The eye detects light stimuli (vision), while the ear detects sound waves (hearing) and also head position/balance. (2) The eye's receptor cells (rods and cones) are located in the retina, while the ear's receptor cells (hair cells) are located in the cochlea (and vestibular apparatus). (3) Both convert their respective stimulus into nerve impulses, which are sent to specific areas of the brain (visual cortex in the occipital lobe for the eye; auditory cortex in the temporal lobe for the ear) for interpretation.
