The connections between the terminal nerve and the olfactory system have been extensively studied in human embryos. olfactory nerve fibers enter the brain at stage 17, fibers from the vomeronasal organ and fibers of the terminal nerve enter the brain at stages 17 and 18. [9] During prenatal development some of the ganglion cells are lost. [7]
The lamina terminalis is a thin layer that forms the median portion of the wall of the forebrain.It stretches from the interventricular foramen (foramen of Monro) to the recess at the base of the optic stalk (optic nerve) and contains the vascular organ of the lamina terminalis, which regulates the osmotic concentration of the blood.
The terminal lamina creates the commissure plate. This structure gives existence to the corpus callosum, the septum pellucidum, and the fornix. The fornix splits into two columns at the front (anterior pillars), and then splits into two posterior crura. These two crura are joined together through the hippocampal commissure.

The following diagram is provided as an overview of and topical guide to the human nervous system: Human nervous system. Human nervous system – the part of the human body that coordinates a person's voluntary and involuntary actions and transmits signals between different parts of the body.
The filum terminale is situated centrally [2] amid the spinal nerve roots of the cauda equina [3] [2] (but is not itself a part of the cauda equina [2]).. The inferior-most spinal nerve, the coccygeal nerve, leaves the spinal cord at the level of the conus medullaris via respective vertebrae through their intervertebral foramina, superior to the filum terminale.

The stria terminalis (or terminal stria) is a structure in the brain consisting of a band of fibers running along the lateral margin of the ventricular surface of the thalamus. Serving as a major output pathway of the amygdala , the stria terminalis runs from its centromedial division to the ventromedial nucleus of the hypothalamus .
