central gray substance of midbrain
|
UBERON_0003040 |
[Periaqueductal gray (PAG; also called the 'central gray') is the gray matter located around the cerebral aqueduct within the midbrain. It plays a role in the descending modulation of pain and in defensive behaviour. The ascending pain and temperature fibers of the spinothalamic tract also send information to the PAG via the spinomesencephalic tract. The spinomesencephalic tract is so-named because the fibers originate in the spine and terminate in the mesencephalon, another name for the midbrain, the part of the brain in which the PAG resides.

|
collagen and cuticulin-based cuticle
|
UBERON_0003049 |
[A type of cuticle composed of highly cross-linked collagens and specialised insoluble proteins known as cuticlins, together with glycoproteins and lipids[WP].] |
|
cuticle
|
UBERON_0001002 |
[Tough but flexible, non-mineral outer coverings of an organism, or parts of an organism, that provide protection. Cuticles are non-homologous, differing in their origin, structure and chemical composition[WP].] |
|
ventral acoustic stria
|
UBERON_0003046 |
[White matter structure containing fibers arising from neurons in the cochlear nuclear complex.] |
|
dorsal longitudinal fasciculus
|
UBERON_0003045 |
[A fiber bundle containing fibers from nuclei of the hypothalamus that project to the dorsal tegmental nucleus and other regions of the midbrain and the pons, as well as fibers originating in the pontine reticular formation and the medullary reticular formation that project to the thalamus and other regions of the forebrain (Carpenter-83). In NeuroNames it is a composite structure consisting of the dorsal longitudinal fasciculus of hypothalamus, the dorsal longitudinal fasciculus of midbrain, the dorsal longitudinal fasciculus of pons and the dorsal longitudinal fasciculus of medulla. (NeuroNames).] |

UBERON_0017690 |
|
|
internal surface of cranial base
|
UBERON_0017692 |
[Internal (endosteal) surface of the base of skull.] |
|
ventricular zone
|
UBERON_0003053 |
[Proliferative region that is part of the ventricular system.] |
|
midbrain-hindbrain boundary
|
UBERON_0003052 |
[The part of the brain that is the morphological boundary between the midbrain and hindbrain and that is the location of an organizing center which patterns the midbrain and hindbrain primordia of the neural plate.] |
|
periderm
|
UBERON_0003055 |
[The outermost layer (or layers, depending on the species) of embryonic skin, essential for the development of the epidermis and establishment of the barrier functions. The periderm derives from the outer layer of the ectoderm.] |
|
roof plate
|
UBERON_0003054 |
[A single row of glia at the dorsal midline of the developing neural tube along the entire anterior-posterior axis. This region provides inductive signals for the specification of neuronal cell types and of the specification of neural crest cells. The cells comprising the roof plate are the precursors to radial glial cells.] |

olfactory placode
|
UBERON_0003050 |
[A thick plate of cells derived from the neural ectoderm in the head region of the embryo that develops into the olfactory region of the nasal cavity.] |
