Basilar processes of the sphenoid and occipital bones.
The base of the skull is fairly well preserved and shows the following characters: The basilar process and the petrous portions of the temporal bones are more massive than usual.
The petro-basilar fissures are large and visibly pervious.
Length of basilar process (notch of vomer to basion) 2.
Length of the upper tooth-rows and zygomatic breadth, when expressed as percentages of the basilar length, and also the actual length of individual teeth vary geographically in the same wavelike fashion as does the width of the rostrum.
The length of the tympanic bullae seems to be actually less, and less in relation to the basilar length, than in other American subspecies of M.
Compared with the skull of the male of pulchra that of latirostra is, by weight, more than one-fourth lighter, has a lesser basilarand orbitonasal length, lesser zygomatic and mastoid breadth and a more nearly flat braincase.
In females the measurements average less, some being the same, and in relation to the basilar length, the bullae are shorter and the skull is shallower.
Sudan Brown to near (l) Antique Brown rather than Buckthorn Brown colors of upper parts and greater size, and in adult male basilarlength more than 45 and hind foot more than 47; from M.
Mustela gracilis, are as follows: Basilar length of Hensel, 38.
This is the case as regards the basilar length of a very old male, no.
Its basilar surfaces, pointing downwards, have their normal influence upon the body.
The one being vertically above the centre of the brain, the other must be vertically below it; one being on the upper the other must be on the basilar surface.
Thus the vertical line separates the indolent from the energetic basilar functions, and all the enfeebling, sensitive, morbid faculties that impair our energies are in the anterior basilar region.
The brain may be divided by a horizontal line from the center of the forehead into its coronal and basilar halves, and by a vertical line from the cavity of the ear, into its frontal and occipital halves.
Gall shows the same frontal preponderance, which led him to the pursuits of intellect instead of ambition, but also shows an immense force of character derived from its extreme breadth and basilar depth.
Insanity, or derangement of the mind and nervous system, belongs to a basilar and anterior location, which we reach through the junction of the neck and jaw (marked Ins.
The maximum upward tendency is at the middle of the superior region, and the maximum downward tendency at the middle of the basilar region, while organs half-way between them are neutral between these opposite tendencies.
Its antagonism must be on the basilar surface, and a little behind the vertical line, as Love is before it.
Similarly the zygomatic breadth slightly exceeds one half of the basilar length, while in Sus cristatus it is less than half.
Thus when the basilar process of the human occipital bone is determined to be the 'centrum' or 'body' of the last cranial vertebra, its general homology is enunciated.
These parts are developed by the formation of three distinct points of ossification, one behind the other, in the basilar cartilage.
The presphenoid might also be considered as a vertebral body, but it develops independently of the basilar plate and trabeculæ.
The processes of this basilar plate, the trabeculæ, are quite unlike anything in the vertebral column.
Now of these bones, the basioccipital is in every way equivalent to a vertebral centrum, for it develops in the basilar plate round the notochord.
It is true that when the process of ossification begins, separate bones are differentiated in the basilarplate one in front of the other, giving an appearance of segmentation.
The basisphenoid appears in the basilar plate, but in front of the notochord, nor does it arise in exactly the same way as the centrum of a vertebra.
Intermediate between these coronal and basilar surfaces are lateral organs which participate in the upward or downward tendency as they approach the highest and lowest surfaces.
The tendency of the coronal region is upward, that of the basilar downward.
The contrast of coronal and basilar development is seen in comparing the benevolent negro Eustace, who received the Monthyon prize for virtue in France with the skull of the cannibal Carib, as figured by Lawrence.
The excessive action of the basilar region exhausts the brain, degrades the soul, and thereby impairing the fountain of life and health, introduces disease and death.
But the normal action of the basilar organs is essential to all the processes of life, and maintains the union of soul and body.
Illustration] Its operation is limited to the region lying around the ears, the basilar region, the tendency of which is to exhaust the spiritual vitality of the brain in ministering to the body.
Murder is therefore not an improper term to express the consummate energy of this basilar organ, if we at the same time understand its gentler manifestations; and Dr.
As the basilar organs act more directly upon the body, their nomenclature will be more suggestive of physiological effects.
In presenting a psychological map of the brain it is almost impossible to separate psychology entirely from physiology in the nomenclature, as the basilar organs relate more to the body than the soul.
In contrast with the chart of Anthropology, the reader will observe that the latter presents the functions of the entire basilar region of the brain, which are marked upon the face and neck in the most proximate locations.
The upper portion of the face corresponds to the expression of the upper surface of the brain, the lower to the occipital region and the posterior inferior portion to the basilar region.
Skull: Shorter and wider (zygomatic breadth expressed in percent of basilar length being, in males, 74.
The length of the skull is second only to that of lenis as also is the length and breadth of the rostrum relative to the basilar length.
Alcoholic liquors injure not only the heart, but often destroy the blood-vessels, chiefly the larger arteries, as the arch of the aorta or the basilar artery of the brain.
It consists essentially of modified ephithelial cells floated upon the auditory epithelium, or basilar membrane, of the cochlea.
It is estimated that there are no less than 3000 of these arches in the human ear, placed side by side in a continuous series along the whole length of the basilar membrane.
The "oblong marrow"; that portion of the brain which lies upon the basilar process of the occipital bone.
Their height varies from ten to thirty feet; their basilar diameters from three to ten feet: their shape generally resembles that of the obelisk.
Anastomosis between trunks of equal size is found where great activity of the circulation is requisite, as at the base of the brain, where the two vertebrals unite to form the basilar artery.
Now try to tie off the arteries in the cranial cavity which will be the vertebrals or the basilar and the common carotids.
Ear more than 58 from notch in dried skin; basilar length of skull more than 63 Sylvilagus aquaticus, p.
Tail blackish or brownish all around (in specimens not having completed molt on tail, white winter pelage may be present); basilar length less than 67 mm.
Ear less than 58 from notch in dried skin; basilarlength of skull less than 63.
There is no overlap in length of body, basilar length, zygomatic breadth, mastoidal breadth or length of nasals.
The basilar membrane, while continuous throughout, may be regarded as made up of many separate cords of different lengths stretched side by side.
Another theory is that the basilar membrane responds to all kinds of vibrations and the analysis of sound takes place in the brain.
The rods of Corti are thought to act as dampers on thebasilar membrane, to prevent the continuance of vibrations when once they are started.
Trace a sound wave from a bell to the basilar membrane, and trace the impulse that it causes from there to the brain.
A third view is that the filaments from the hair cells, rather than the basilar membrane, respond to the vibrations and in turn stimulate the terminations of the nerve fibers.
The nerve fibers terminate upon the membrane known as the basilar membrane, which separates it from the scala tympani.
From here the vibrations pass through the channels of the cochlea and set into vibration the contents of the scala media and different portions of the basilar membrane.
