研究人员在Strumigenys中发现了两个新的胸腺,可能有助于刺功能. 这些腺体是独一无二的这种属,表现出不同物种的多样化发展.
科学领域:
- 昆虫学 昆虫学是一门学科.
- 昆虫的解剖学 昆虫的解剖学
- 腺体系统 腺体系统
背景情况:
- 类拥有高度发达的外分泌系统,有10个独特的腺体.
- 以前的研究已经确定了Strumigenys腺体解剖学的复杂性.
研究的目的:
- 为了调查和描述新发现的Strumigenys的胸腺.
- 研究这些新型腺体的形态和潜在功能,与刺痛解剖学和行为有关.
主要方法:
- 在18个Strumigenys物种 (工人和女王) 中对胸腺进行显微镜检查.
- 腺体细胞结构的分析,包括上皮细胞形态,结点和相关的皮质特征.
- 对不同物种的腺体发育及其与生态角色的潜在相关性的比较分析.
主要成果:
- 在Strumigenys的工人和女王中发现了两个新的胸腺,位于第6和第7个胸腺上.
- 这些上皮腺具有专门的细胞结构 (数字间,光滑的内等质网膜,微) 并且位于刺痛基附近.
- 腺体的发育有所不同,社会寄生虫Strumigenys mutica中最明显的腺体和Strumigenys sauteri中基本的/缺失的腺体,可能与捕捉刺独立的猎物有关.
结论:
- 在Strumigenys中新发现的胸腺腺体在解剖学上是截然不同的,并且可能与刺机制相关的功能.
- 观察到的腺体发育的变化表明该属内的功能性适应,可能与养策略或社会寄生虫有关.
- 这些腺体在费洛蒙产生或跟踪过程中的作用可以排除,因为该属缺乏跟踪行为.

Exocrine Glands: Methods of Secretion
Merocrine Secretion
Merocrine secretion is the most common type of exocrine secretion. The secretions are enclosed in vesicles and moved to the cell's apical surface, where the contents are released by exocytosis. For example, mucous, a watery secretion rich in the glycoprotein mucin, is a merocrine secretion. The eccrine...
Exocrine Glands: Types of Secretions
Serous glands produce watery secretions rich in digestive enzymes and proteins. The constituent cells of the serous gland have centrally located nuclei and eosinophilic secretory granules in the cytoplasm. The parotid gland is an example of a serous gland. It secretes saliva, which contains enzymes, such as lipases and...

Sweat glands are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There...
