The four round swellings that is located in the dorsal portion of the midbrain. |
The correct answer is Option (4) – The four round swellings that is located in the dorsal portion of the midbrain. The term "corpora quadrigemina" refers to the four round swellings located in the dorsal portion of the midbrain. The forebrain consists of cerebrum, thalamus and hypothalamus. Cerebrum forms the major part of the human brain. A deep cleft divides the cerebrum longitudinally into two halves, which are termed as the left and right cerebral hemispheres. The hemispheres are connected by a tract of nerve fibres called corpus callosum. The midbrain is located between the thalamus/hypothalamus of the forebrain and pons of the hindbrain. A canal called the cerebral aqueduct passess through the midbrain. The dorsal portion of the midbrain consists mainly of four round swellings (lobes) called corpora quadrigemina. |
