Numerous nerve fibers lay supraependymally, singly or in groups, between the microvilli and cilia of the ependymal cells. Varicosities occurred along the fiber, often in close succession. The intraventricular nerve endings were flask-shaped. Vesicles were present in the cytoplasm of the nerve ...
Describe the structure of a nerve, and state the location of nerves and tracts. 描述神经的结构,并指出神经和神经纤维束的位置。 Answer: A nerve contains bundles of peripheral neuron fibers surrounded by connective tissue. Each nerve fiber within a nerve is surrounded by a white myelin sheath; ...
Nerve tissues contain hierarchically ordered nerve fibers, while each of the nerve fibers has nano-oriented fibrous extracellular matrix and a core-shell structure of tubular myelin sheath with elongated axons encapsulated. Here, we report, for the first time, a ready approach to fabricate biomimetic...
Answer to: Compare the structure of a nerve cell to the structure of a muscle cell. What explains the anatomical similarities? What are the main...
The intervertebral foramen between C4, C5, C6 is relatively small and the diameter line of nerve root is comparatively large, so the nerve root at C4, C5, C6 is most likely to be pressed. 展开 关键词: cervical nerve fiber anatomy cervical syndrome microinvasive surgery ...
The stimulus that causes the skeletal muscle contraction is considered the arrival ofnerve impulsesfromthe brainandspinal cordthrough themotor nerve cellswhich their terminals arborizations are connected firmly with the muscle fiber, forming a neuro-muscular junction,The synapsehas synaptic vesicles ...
weight. Strain - % stretching of fibers. Elastic limit - point at which the elasticity of the fiber is lost. Failure - point at which the fiber breaks. Collagen Collagen molecule - a triple helix of three extended protein chains wrapped around one another. Numerous rodlike collagen molecules ...
The glaucomas are a group of relatively common optic neuropathies, in which the pathological loss of retinal ganglion cells causes a progressive loss of sight and associated alterations in the retinal nerve fiber layer and optic nerve head. The diagnosis and management of glaucoma are often dependen...
Axons are the usually long process of a nerve fiber that generally conducts impulses away from the body of the nerve cell. This book is intended to summarize recent findings covering morphological, physiological, developmental, computational and pathophysiological aspects of axons. It attempts to cover...
