(the first optic neuropile), and long visual fibres, which project directly to the medulla

De Castro, however, in 1927 demonstrated that the anatomy of the glomus could in no way be compared to that of the suprarenal medulla.

-
The most cogent theory that supports the occasional finding of subcutaneous islands of ependyma in the postcoccygeal region in infants is that these lesions originate from extramedullary ependymal rests.
-
Other lesions obsd. included focal hyperplasia of the adrenal medulla in high dose male mice given THPS and follicular cell hyperplasia of the thyroid gland in high dose female mice given THPC.
-
These are marked off from each other by intervening constrictions, and are named the fore-brain or prosencephalon, the mid-brain or mesencephalon, and the hind-brain or rhombencephalonthe last being continuous with the medulla spinalis.

-
Tumours growing _in the substance of the cord_ are nearly as common as extra-medullary growths, and as the growth is usually sarcoma, glioma, tuberculoma, or gumma, and infiltrates the cord, it is seldom capable of being removed by operation.

Particularly in the pathological examination, we discovered that it could activate and proliferate cells in lymph follicles, geminal centre, paracortical zone and medullary cord of lymph nodes.
-
Now, _Polyporus dryadeus_ and _P. igniarius_ are such fungi; their hyphæ excrete a ferment which completely destroys the starch grains in the cells of the medullary rays of the oak, a tree very apt to be attacked by these two parasites, though _P. igniarius_, at any rate, attacks many other dicotyledonous trees as well.
Scientific American Supplement, No. 643, April 28, 1888
-
The glomerular tufts were shrunken or necrotic and renal medullary rays were congested.
-
The cerebrum, pons, and medulla were hypoplastic.
-
Within the adrenal medulla dopamine is converted to norepinephrine and epinephrine.
-
The brainstem consists of the midbrain, pons and medulla, structures located deep in the back of the brain.
-
At this point, it gives off collaterals and ascends ipsilaterally in the fasciculus gracilis (or cuneatus) to synapse in the nucleus gracilis (or cuneatus) in the caudal medulla.

You load up a suffering organ with grub that's so rich it affects the imagination; consequently, when the razmataz, in a state of coma, projects itself into the _medulla oblongata_ --

Tsudzimura15, that the effects of splanchnic nerve stimulation are transmitted to the cells of the suprarenal medulla by the release of acetylcholine in that tissue.

-
Nerve cells are largely aggregated in the gray substance of the brain and medulla spinalis, but smaller collections of these cells also form the swellings, called ganglia, seen on many nerves.

-
What I've hopefully done is lit a spark in your brains that'll burn a tunnel from your prefrontal lobes to your medulla oblongata.
-
For example, our results may help explain the motions of secretory granules in chromaffin cells of the adrenal medulla.
-
These cells and their processes constitute a series of association or intersegmental neurons (Fig. 668), which link together the different parts of the medulla spinalis.
IX. Neurology. 3. The Spinal Cord or Medulla Spinalis
-
The cortical tissue in the area between the medullary pyramids constitutes the renal columns of Bertin.
-
Microscopy revealed acellular laminated membranes with a germinal layer within the medullary cavity of the tibia and fibula.
-
It consists of (a) the myelencephalon, comprising the medulla oblongata and the lower part of the fourth ventricle; (b) the metencephalon, consisting of the pons, cerebellum, and the intermediate part of the fourth ventricle; and (c) the isthmus rhombencephali, a constricted portion immediately adjoining the mid-brain and including the superior peduncles of the cerebellum, the anterior medullary velum, and the upper part of the fourth ventricle.
IX. Neurology. 4a. The Hind-brain or Rhombencephalon
-
It is a general practice of the orthopaedic surgeons to strip the periosteum, to ream the medullary cavity etc, which may easily cause injury of the nutrient artery of the long bones.
-
Leptin increases activity in sympathetic nerves in the kidney, brown adipose tissue, hind limbs, and adrenal medulla.
-
You see, that contains the medulla oblongata, which is the heart, blood vessel and breathing center of the brain.

Horsley has demonstrated certain medullated fibers running in the epineurium and terminating in small spheroidal tactile corpuscles or end bulbs of Krause.
IX. Neurology. 1. Structure of the Nervous System
-
Dorsal to the olivary nuclei is the extensive reticular formation of the medulla, composed of diffusely disposed neurons interspersed by ascending and descending myelinated axons belonging to a variety of pathways.
-
The word sensorium is used to express not only the medullary part of the brain, spinal marrow, nerves, organs of sense and muscles, but also at the same time that living principle, or spirit of animation, which resides throughout the body, without being cognizable to our senses except by its effects. additional notes contents table of contents
