| brachium colliculi superioris | A band of fibres of the optic tract bypassing the lateral geniculate body to terminate in the superior colliculus and pretectal region. Synonym: brachium colliculi superioris, brachium quadrigeminum superius, superior quadrigeminal brachium. (05 Mar 2000) |

| brachium conjunctivum cerebelli | A large bundle of nerve fibres that originate from the dentate and interpositus nuclei and emerges from the cerebellum in the rostral direction, along the lateral wall of the fourth ventricle. The bundle submerges from the dorsal surface of the brainstem into the mesencephalic tegmentum, where all of its fibres cross in the massive decussation of the superior cerebellar peduncles. Part of the bundle terminates in the contralateral red nucleus; the bulk of the fibres continue rostrally to parts of the ventral intermediate nucleus of thalamus, ventral posterolateral nucleus of thalamus, and central lateral nucleus of thalamus. Synonym: pedunculus cerebellaris superior, brachium conjunctivum cerebelli. (05 Mar 2000) |
| brachium of inferior colliculus | A fibre bundle passing from the inferior colliculus on either side of the brainstem along the lateral border of the superior colliculus to the posterior part of the thalamus where it enters the medial geniculate body. It forms part of the major ascending auditory pathway. Synonym: brachium colliculi inferioris, brachium quadrigeminum inferius, inferior quadrigeminal brachium. (05 Mar 2000) |
| brachium of superior colliculus | A band of fibres of the optic tract bypassing the lateral geniculate body to terminate in the superior colliculus and pretectal region. Synonym: brachium colliculi superioris, brachium quadrigeminum superius, superior quadrigeminal brachium. (05 Mar 2000) |
| brachium pontis | The largest of three paired cerebellar peduncles, composed mainly of fibres that originate in the pontine nuclei, cross the midline in the ventral part of pons, and emerge on the opposite side as a massive bundle arching dorsally along the lateral side of the pontine tegmentum into the cerebellum; its fibres are distributed chiefly to the cortex of the cerebellar hemisphere. Synonym: pedunculus cerebellaris medius, brachium pontis. (05 Mar 2000) |
| brachium quadrigeminum inferius | A fibre bundle passing from the inferior colliculus on either side of the brainstem along the lateral border of the superior colliculus to the posterior part of the thalamus where it enters the medial geniculate body. It forms part of the major ascending auditory pathway. Synonym: brachium colliculi inferioris, brachium quadrigeminum inferius, inferior quadrigeminal brachium. (05 Mar 2000) |
| brachium quadrigeminum superius | A band of fibres of the optic tract bypassing the lateral geniculate body to terminate in the superior colliculus and pretectal region. Synonym: brachium colliculi superioris, brachium quadrigeminum superius, superior quadrigeminal brachium. (05 Mar 2000) |
| Bracht manoeuvre | Delivery of a foetus in breech position by extension of the legs and trunk of the foetus over the symphysis pubis and abdomen of the mother; the foetal head is born spontaneously as the legs and trunk are lifted above the maternal pelvis, and as the body of the infant is extended by the operator.
