Summary
This study argues for a history of chiropractic vertebral subluxation (CVS) theory using primary sources. Understanding CVS history can help resolve professional terminology debates and foster future philosophical discussions.
Area of Science:
- Chiropractic Philosophy
- History of Medicine
Background:
- The chiropractic profession exhibits a significant dichotomy in its understanding and use of subluxation terminology.
- This complex issue involves social, economic, cultural, and scientific dimensions within the field.
Purpose of the Study:
- To establish a rationale for a comprehensive history of chiropractic vertebral subluxation (CVS) theory.
- To utilize primary sources to trace the evolution of CVS theory within the chiropractic profession.
Main Methods:
- Analysis of primary source documents related to chiropractic vertebral subluxation theory.
- Historical research to track the development of key ideas and concepts.
Main Results:
- Identification of diverse perspectives and historical trajectories within CVS theory.
- The proposed historical approach offers a foundation for understanding current debates.
Conclusions:
- A historical perspective grounded in primary sources is crucial for addressing the subluxation terminology dichotomy.
- This work aims to facilitate further philosophical dialogue and advance the understanding of CVS theory in chiropractic.

01:27Muscles of the Vertebral Column
3.1K
The back muscles that lie deep into the thoracolumbar fascia are called intrinsic or true back muscles. These muscles are divided into four layers: superficial, intermediate, deep, and deepest layers.
Superficial Layer:
The superficial layer consists primarily of the splenius muscles, which include the splenius capitis and splenius cervicis. These muscles are mainly responsible for the head and cervical spine movements, including extension, rotation, and lateral bending. The splenius capitis...

01:28Articulations of the Vertebral Column
3.0K
In addition to being held together by the intervertebral discs, adjacent vertebrae also articulate with each other at synovial joints formed between the superior and inferior articular processes called zygapophysial joints (facet joints). These are plane joints that provide for only limited motions between the vertebrae. The orientation of the articular processes at these joints varies in different regions of the vertebral column and serves to determine the types of motions available in each...

01:16Vertebral Column: Regions and Curvature
5.9K
The vertebral column or spine is a flexible column that supports the head, neck, and body and allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

R is a powerful software environment for statistical computing and graphics. Originating as an implementation of the S language, developed at Bell Laboratories, R has evolved into a robust, open-source statistical software favored by statisticians and data scientists worldwide. Its comprehensive suite includes data manipulation, calculation, and graphical display capabilities, making it versatile for data analysis and visualization. Its programming language is at the core of R's...

02:15SN1 Reaction: Stereochemistry
10.2K
This lesson provides an in-depth discussion of the stereochemical outcomes in an SN1 reaction.
In the first step of an SN1 reaction, the bond between the electrophilic carbon and the leaving group ionizes to generate the carbocation intermediate. The second step of the mechanism is the nucleophilic attack.
In the formed carbocation, the positively charged carbon is sp2 hybridized with a trigonal planar geometry. As all the three substituents lie on the same plane, a plane of symmetry for the...

02:05SN1 Reaction: Kinetics
9.5K
In an SN2 reaction, the reaction rate depends on both the type of nucleophile and the substrate. A hindered tertiary alkyl halide is practically inert to the SN2 mechanism despite using a strong nucleophile.
However, Sir Christopher Ingold and Edward D. Hughes, who studied the kinetics of various nucleophilic substitution reactions, noticed that a tertiary alkyl halide does undergo a nucleophilic substitution reaction in the presence of a weak nucleophile. While studying the substitution...
