The cervical region helps to support the head and allows for movement and rotation of the skull. The thoracic region helps to protect the heart and lungs. The low back bears the weight of the upper body and has the largest vertebrae. Read Spinal Nerves Function & Diagram Lesson ...
Amazing diagram of the path of the vagus nerve and its branches in the neck, thorax, and abdomen, from Wilson-Pauwels et al. (1988). The gonads aren’t drawn here, but they do receive vagal innervation. This isn’t new to science, it’s just one of the cool little quirks of human...
Notes: Thelateral femoral cutaneous nervecan arise from the femoral nerve, but also can simply be an independent branch of the lumbar plexus, typically arising from the second and third lumbar vertebrae (L2–L3). The lateral femoral cutaneous nerve emerges from the lateral border of the psoas m...
A cross-sectional diagram of the pelvis shows the visceral peritoneum encasing the mesorectum with the areolar tissue plane between the visceral peritoneum and the parietal peritoneum posteriorly (Figure 9-3B). The parietal peritoneum covers a nerve and venous plexus over the sacrum and the ...
Pain along the sciatic nerve usually caused by a herniated disk of the lumbar region of the spine and radiating to the buttocks and to the back of the thigh. [Middle English, from Medieval Latin, from feminine ofsciaticus,of the hip; seesciatic.] ...
6.fusion- correction of an unstable part of the spine by joining two or more vertebrae; usually done surgically but sometimes done by traction or immobilization spinal fusion correction- treatment of a specific defect; "the correction of his vision with eye glasses" ...
Fig. 1: Schematic diagram showing types of DRG-lesioned mice created in this study. Two major spinal afferent populations innervate the colon and rectum. They arise from the thoracolumbar DRG and the lumbosacral DRG. To study their functions, mice lacking either pathway were created by bilateral...
Images of an ultrasound-guided pericapsular nerve group block. A The left hip in the supine position. B Orientation of the ultrasound probe. C The needle tip was positioned between the psoas tendon and the pubic ramus by using an in-plan approach. AIIS, anterior inferior iliac spine; FA,...
Diagram of a motor end-plate in striated muscle. This is the synaptic contact between a motor nerve fiber and a striated muscle cell. As the motor axon approaches the muscle cell, it loses its myelin sheath and the neurilemma cells form a “lid” over the myoneural junction. The motor ...
