The human brain is divided into forebrain, midbrain and hindbrain. Select correct option which contains only correct option. i. The cerebral cortex contains motor areas, sensory areas and large association areas ii. Association areas are clearly sensory and motor in function and it related with complex functions like inter sensory association, memory and communication iii. Thalamus is a major coordinating centre for sensory and motor signalling iv. The hypothalamus contains a number of centres which control body temperature, urge for eating and drinking v. The inner parts of cerebral hemispheres, amygdale, hippocampus, etc., form a complex structure called the limbic lobe or limbic system vi. Along with the hypothalamus, limbic system is involved in the regulation of sexual behaviour, expression of emotional reactions and motivation vii. A canal called the cerebral aqueduct passes through the hindbrain viii. The medulla contains centres which control respiration, cardiovascular reflexes and gastric secretions

Read the following statements about the human nervous system : (i) A multipolar neuron is with one axon and two or more dendrites , found in the cerebral cortex. (ii) in resting condition, the sodium-potassium pump transports 3 Na^(+) inwards and 2K^(+) outwards the cell. (iii) Midbrain and hindbrain form the brain stem including the cerebellum. (iv) the pons of the hindbrain is directly connected to the spinal cord to control respiration. How many statement/s from above is/are incorrect ?

Make corrections wherever you find mistake in spellings/words in the following parapraphs/sentences. (A) During the period of senescence, a gradual addition occurs in the structure and functioning of an organ or organism which is characterised by the accumulation of active metabolic materials and increase in dry weight. (B) When the movement of curvature is produced by diffused stimuli and affects the whole plant uniformly, it is of tropic type. If the curvature is produced by directional mutimuli and does not affect the whole plant, it is of nastic type. (C) Shoot elongation in some dwarf varieties and barley endosperm test are used as bioassays for auxins and Avena curvature test is used as bioassay for ethylene.

(a) Name two systems which taken together perform the functions of control and coordination in human beings. (b) What does the central nervous system in humans consist of? What is the job of the central nervous system? (c) Give the various functions of brain.
