Recent Examples on the Web Dickman has found that lesser hairy-footed dunnarts (Sminthopsis youngsoni) and Wongai ningaui (Ningaui ridei)—small mouselike marsupials in Australian deserts—preferentially eat the abdomens and thoraxes of their insect, spider and centipede prey. — Stephanie Pappas, Scientific American, 11 Apr. 2023 Another intern taught her how to spread the jam evenly, monitor the drying process, then use tweezers to assemble the head, thorax, abdomen and wings. — Julia Moskin, New York Times, 9 Jan. 2023 By distorting the shape of the thorax, the orientation of the beating wings is changed. — Carl Engelking, Discover Magazine, 26 Mar. 2014 No dry-fly hatch in North America incites as much frenzy among trout flyfishermen as the emergence of Pteronarcys californicus —the giant stonefly (a.k.a. the salmonfly, a nickname that comes from the orange color on the thorax), in the Western trout rivers of the Rockies. — Keith Mccafferty, Field & Stream, 16 June 2020 Bacteria and viruses settle into the crevices and cracks between thorax and head, and begin to multiply. — Rebecca Kreston, Discover Magazine, 9 May 2012 Then the researchers studied each specimen directly and took a piece of its thorax for DNA sequencing. — Meghan Bartels, Scientific American, 8 Mar. 2023 The Signature HD is built on a tube as thin as a wasp’s thorax, but the thrusting ¼ MOA turrets and dual parallax/illumination module are a bit proud. — Andrew Mckean, Outdoor Life, 18 Aug. 2020 The colo...

There are many different reasons you may have pain in this region. Many causes aren’t serious, but some, like a fractured vertebra or herniated disk, require medical attention. Most people have • 7 cervical vertebrae in your neck • 12 thoracic vertebrae in your middle and upper back • 5 lumbar vertebrae in your lower back • 5 fused vertebrae that make up your sacrum • 4 fused vertebrae that make up your tailbone Pain in your middle and upper back is known as thoracic back pain. Keep reading to learn more about the potential causes of thoracic back pain. Symptoms of thoracic back pain vary depending on the underlying cause of your pain. You may have: • sharp pain • a dull ache at rest • pain during certain movements • stiffness • swelling • muscle spasms • cramping • sudden pain with sneezing, coughing, or laughing • numbness around your rib cage and chest • loss of • numbness, tingling, or loss of movement in your legs Thoracic back pain is very common and estimated to affect Here are some of the potential causes. Muscle and connective tissue pain A variety of muscle, tendon, or ligament injuries can cause pain in your back. These injuries can either be acute, meaning they onset suddenly, or chronic. Chronic injuries are caused by repetitive strain. Potential causes of pain include: • sports- or exercise-related injuries like muscle strains or ligament sprains • motor vehicle crashes or falls • carrying heavy objects • certain sleeping positions • repetitive stress from • ...

This guide gives a general overview of the anatomy of the thoracic spine. It also includes some facts regarding pathophysiology in this region. The sagittal plane alignment of the Thoracic spine is on average 35% (normal range is 20° to 50°). Important Structures The important parts of the thoracic spine include: • • Joints • Structure/motion • • • • Bones (vertebrae and ribs) [ | ] The human spine is made up of 24 spinal bones, called vertebrae. Vertebrae are stacked on top of one another to create the spinal column. The spinal column is the body’s main upright support. • The middle 12 • T5-T8 tend to be the most “typical” in that they contain features present in all thoracic vertebrae. T5-T8 have the greatest rotation ability of the thoracic region. • T1 - superior costal facets are “whole” costal facets. They alone articulate with the • T11 and T12 are atypical - contain a single pair, “whole,” costal facet that articulate with the 11 and 12 • The primary characteristic of the thoracic vertebrae is the presence of costal facets. There are 6 facets per thoracic vertebrae: 2 on the transverse processes and 4 demifacets. The facets of the transverse processes articulate with the tubercle of the associated rib. The demifacets are bilaterally paired and located on the superior and inferior posterolateral aspects of the vertebrae. They are positioned so that the superior demifacet of inferior vertebrae articulates with the head of the same rib that articulates with the inferi...

Synonyms: Vertebrae T1-T12 The twelve thoracic vertebrae are intervertebral discs. However, they are various anatomical features that make them quite dinstinct compared to other groups of vertebrae. In addition, several thoracic vertebrae are 'special' in a way, either in terms of its structure or by providing an important landmark that physicians use to orientate themselves and locate other anatomical structures. Two muscles also interact with those twelve vertebrae, these being the Key facts Main characteristic 12 vertebrae connected with intervertebral discs (nucleus pulposus + anulus fibrosus) Anatomical characteristics Body: heart-shaped massive that increase in size as descending to the lumbar vertebrae Spinous process: dorsal bony prominence Costal facets (superior, inferior, transverse): articulation surfaces for head of the rib Transverse process: bony process that arises from the vertebral arch, intended for the attaching of the rib tubercle Superior and inferior articular facets: articulation surfaces for adjacent (superior and inferior) vertebrae Lamina: bony imbrication that covers the subjacent vertebrae and connect with pedicles to protect the spinal cord Intervertebral foramen: paired foramina (one left, one right) intended for the exiting nerve roots Vertebral foramen: large opening posterior to the body that forms spinal canal through which the spinal cord passes Distinguishing features Presence of facets for the joints with the ribs (all except the 11th ...
