soft tissue layer around the bones retained traces of ferrous iron, a relic left over from haemoglobin that was also trapped in the sample.
Microscopic analyses of annual
tissue layers in tooth roots of excavated animals indicated that dogs almost always had been killed in the cold half of the year, from late fall through winter.
There is under - development (hypoplasia) of the
eye tissue layer called the choroid.
Synchrotron X-ray imaging on different species showed that the transmission of the sound from the oral cavity to the inner ear has been optimized by two evolutionary adaptations: a reduced thickness of the tissue between the mouth and the inner ear and a smaller number of
tissue layers between the mouth and the inner ear.
This technique allows doctors to conduct «virtual autopsies,» adding or removing bone and
tissue layers as needed.
By the 10th day of a human embryo's development, molecular signaling that initiates tooth formation is taking place between two basic
embryonic tissue layers.
Hydra vulgaris is shown with its two
tissue layers transgenically labeled: ectoderm (outer layer) in green; endoderm (inner layer) in magenta.
Jeff Lichtman, a neuroscientist at Harvard University, has built a device called an ultramicrotome that uses a diamond knife to shave
brain tissue layer by layer.
Anatomically, the mucosa of the head and neck can be divided into a layer of stratified squamous epithelium and an underlying connective
tissue layer known as the lamina propria (Table 2).
He and the Vereide Group grow precursors of human arterial cells, build colonies of dendritic cells (cells which can alert the rest of the immune system to the presence of a tumor), and use chick embryos to study the formation of
early tissue layers for a possible future in which complex tissues, or even organs, can be grown to replace diseased, wounded, or malfunctioning ones.
The
thin tissue layer separating the epidermis from the dermis below is extremely fragile, causing blistering, peeling, and fraying of the skin, leaving wounds that can be deadly and raising the risk of skin cancer.
Progressive Retinal Atrophy (PRA) is an inherited disease of the retina (
tissue layer at the back of the eye containing the rods and cones) where the retina slowly degenerates with time.
These organisms live naturally in the skin but when the skin is irritated, they gain access to
inner tissue layers and proliferate.
Colobomas are seen at and near the optic nerve head as outpouchings or «pits» in the
eye tissue layers.
The dermal - epidermal junction (DEJ) is where the dermis (outer skin layer) connects to the epidermis (
the tissue layers just beneath the skin).
Her lab uses Hydra genetically engineered to light up the animals» two
tissue layers, which allowed the researchers to observe the hydras» feeding process on a cellular level.
What's more, the CaP / gel / Ti rods bonded to the surrounding bone directly, with no intervening soft
tissue layer.
bilaterians: A clade of animals whode members share: bilateral symmetry, are triploblastic (three
tissue layers: ectoderm, mesoderm, endoderm), and with HOX genes in one or more clusters with the genes within a cluster arranged in the same order as the body parts they affect.
Multi-photon imaging of the embryonic eye: A false - coloured image showing a cutaway through the invaginating lens placode (blue
tissue layer) situated within the optic cup (yellow tissue layer) of a 2.5 - day chick embryo.
This experiment led the team to the cortex,
the tissue layer directly beneath the epidermis, as the region responsible for changing root growth directions in response to water.
A thread connecting these different cancer types is that most have important known environmental risk factors and all tend to arise in
the tissue layers directly exposed to the environment.
«Synovium — the thin soft -
tissue layer that covers and lubricates your tendons — has estrogen receptors in it, so when your hormones fluctuate, it can swell.»
Ginger and tulsi tea have a great affinity to
this tissue layer and nourish it through their warming and building qualities.
