Study the following statements w.r.t. midbrain (a) It is located between hypothalamus of the forebrain and pons of hindbrain. (b) Cerebral aqueduct passes through midbrain. (c) It is a part of brain stem along with some portions of hindbrain. (d) The dorsal portion of midbrain comprises the limbic lobes. The correct statements are

III. The ciliary body itself continues forward to form a pigmented and opaque structure- iris. IV. The membranous labyrinth is filled with a fluid called endolymph. How many of the given statements are correct?

Read the following statements and find out the incorrect statements. a. The ventral portion of the midbrain consists mainly of four round swellings (lobes) called corpora quadrigemmina. b. Midbrain and hindbrain form the brain stem. c. Cerebellum consists of fibre tracts that interconnect different regions of brain. d. The midbrain receives and integrates visual, lactile and auditory inputs. e. Limbic system is concerned with olfaction and autonomic responses.

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 ?
