概括
圣化和 lumbarization 涉及脊椎转变,23个前圣脊椎 (PSV) 与较短的肋骨相连,25个PSV与较长的肋骨相连. 这些独特的脊椎模式表明,对骨发育有不同的遗传影响.
科学领域:
- 人类解剖学和骨形态学
- 发育生物学和遗传学
- 脊椎的变化 脊椎的变化
背景情况:
- 圣化和 lumbarization 是脊椎变异影响腰椎和十字骨之间的过渡.
- 这些条件通常是独立研究的,但它们作为一对双元的潜在关系需要进行调查.
- 了解这些变异对于诊断脊髓疾病和理解人类骨演变至关重要.
研究的目的:
- 调查圣化和 lumbarization 作为潜在的配对,脊椎变异的相反表达.
- 确定这些变异是否与特定数量的前圣节脊椎 (PSV) 相关,即23个PSV用于圣化和25个PSV用于 lumbarization.
- 探索这些脊椎变异与其他肋脊椎变化的关联.
主要方法:
- 对431名女性和1405名男性 (20-49岁) 的骨遗骸分析,来自20世纪和21世纪.
- 数据收集包括PSV和十字脊椎的计数,V7肋骨的存在,腹膜脊椎位置,以及特定脊椎的横向过程/肋骨长度 (V5-V9,V18-V19,V21-V22).
主要成果:
- 在PSV计数中观察到基于性别的显著差异.
- 患有23个PSV的个体表现出较短的肋骨 (V18-V19) 和更高的频率的6个椎.
- 患有25个PSV的个体表现出更长的肋骨 (V18-V19) 和更高的5个椎的频率.
结论:
- 患有23PSV和25PSV的个体分别在胸椎-腰椎和腰椎- sacral 结处表现出后部和前部的同源转变.
- 只有在25个PSV的个体中观察到交叉骨-骨边界的转变.
- 不同的同时发生的肋骨脊椎转变表明,神圣化和腰椎化背后存在着不同的遗传影响.

Vertebral Column: Regions and Curvature
3.5K
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...

Articulations of the Vertebral Column
1.8K
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...

Spinal Nerves: Plexus II
533
The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...

General Structure of a Vertebra
2.6K
A typical vertebra, with the exception of the sacrum and coccyx, consists of a body, a vertebral arch, and seven different projections termed processes. The anterior portion of the vertebrae, the body, supports about half the body’s weight. The vertebral bodies progressively increase in size and thickness from the cervical region to the lumbar region of the vertebral column. The intervertebral discs present between the bodies of adjacent vertebrae firmly unites them, forming a continuous...

Spinal Nerves: Anatomy
2.4K
Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
There are 31 bilateral pairs of spinal nerves, each emerging from the spinal cord through the intervertebral foramina—openings between adjacent vertebrae. These nerves are...

Abdominal Regions and Quadrants
7.7K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...
