3 Surface Anatomy Of The Brain
In this laboratory session, we will study the surface anatomy of the human brain. Below, you will be presented with a number of figures and asked to label or color certain structures in each figure.
3.1 A Dorsal View Of A Human Brain.
- Write “ANTERIOR’ and “POSTERIOR“ next to the arrowhead pointing in the corresponding direction:
- Write “LH“ over the left hemisphere and “RH“ over the right hemisphere in figure 1 below.
- Mark the longitudinal cerebral fissure with a sequence of “x”’s

3.2 A Dorso-Lateral View Of A Human Brain.
- Write “ANTERIOR’ and “POSTERIOR“ next to the arrowhead pointing in the corresponding direction
- Trace the Sylvian fissure using a black marker
- Trace the central sulcus from the midline to the Sylvian fissure using a black marker

3.3 A Lateral View Of A Human Brain.
- Write “ANTERIOR’ and “POSTERIOR“ next to the arrowhead pointing in the corresponding direction
- Write “DORSAL“ and “VENTRAL“ next to the arrowhead pointing in the corresponding direction
- Write “CEREBRUM“ and “CEREBELLUM“ next to the corresponding structures

3.4 A Ventral View Of A Human Brain.
- Write “LH“ over the left hemisphere and “RH‘ over the right hemisphere in figure 1 below.
- Write “LCblH“ over the left hemisphere of the cerebellum and “RCblH‘ over the right cerebellar hemisphere in the figure below.
- Write “Pons“ over the corresponding structure in the figure below.
- Write “MO“ denoting the medulla oblongata over the corresponding structure in the figure below.
- Write “ANTERIOR’ and “POSTERIOR“ next to the arrowhead pointing in the corresponding direction.
