Fill in the blank: A fascicle of axons is surrounded by a connective tissue sheath called the ___. Fill in the blank: The nerve supplies the biceps brachii muscles What long tendon is involved in the hip joint? What other joint does it have a role in s...
A nerve is: a. a neuron. b. the functional unit of the nervous system. c. a part of the central nervous system. d. a bundle of sensory fibers and motor dendrites. e. a bundle of axons and/or dendrites wrapped in c...
Osterix+ cells express the osteoblast-specific marker osterix [37] and therefore allow characterization of osteoprogenitors. The endoneurium contains the axons and their supporting glial cells, called Schwann cells, embedded in loose collagen fibrils within unique fascicles surrounded by multiple layers...
is generated by the sun through the scattering of sunlight in the atmosphere (Rayleigh scattering; Strutt1871). It is characterized by systematic changes in the degree and angle of polarization (Fig.1a,b). Because this pattern is tightly linked to the position of the sun, it moves with the ...
The tumor capsule is often covered by tortuous blood vessels. Axons are not usually present within the tumor, which allows schwannomas to be removed without damages to the underlying nerve fascicles [8]. Clinical presentation of schwannomas is unclear and unspecific. Symptomatic schwannomas in the...
and the perineurium that encloses a fascicle and the endoneurium that holds the neurons and blood vessels together within a fascicle. Due to these multiple layers of lamination around an axon, the amplitude of a peripheral nerve signal is usually very small, can be around 5 – 20μV [11...
INTRODUCTION During insect neurogenesis, an orthogonal pattern for the nervous system, espe- ciaUy the complex network of neural fascicles, is established in stepwise manner[1,2]. Genetic approaches have led to the identification of a number of genes that have been implicated in these process [...
5a). We manufactured MOSD with four mini-LEDs that covered half of C7 nerve and turned the device 180° to cover the entire C7 during the stimulation experiment. Immunohistochemistry staining revealed that axons were densely packed in both the distal and proximal side of C7 nerve (Fig. 5b)....
The longitudinal intrafascicular electrode (LIFE) is a fine wire that can provide access to a discrete population of axons within a peripheral nerve fascicle. Some applications require, or would benefit greatly from, technology that could provide access to multiple discrete sites in several fascicle...
Samples for electron microscopy were taken from the region of the superior longitudinal fascicle and from the transitional white matter between temporal and frontal lobe where the uncinate and inferior occipitofrontal fascicle merge. We measured the inner diameter of cross sections of myelinated axons....
