概括
蝙蝠鼻轮机在回声定位物种中更简单,特别是那些使用鼻声定位的物种. 食蝙蝠的嗅觉表面积更大,突出显示了轮式多功能性.
科学领域:
- 比较解剖学的比较解剖学.
- 进化生物学是进化的生物学.
- 生物声学是一种生物声学.
背景情况:
- 假设鼻轮,折叠的内部鼻骨,在具有喉回声定位和昆虫捕食的蝙蝠中被简化.
- 以前的研究表明,蝙蝠的回声定位,饮食和轮复杂性之间存在联系.
研究的目的:
- 广泛测试关于蝙蝠轮机解剖学简化的假设,与喉回声定位和切罗伯特的饮食有关.
- 调查轮形态在鼻声和嗅觉功能的作用.
主要方法:
- 组织学和增强的微型计算机断层扫描 (微型CT) 用于检查鼻轮.
- 分析了来自54个物种的83只成年蝙蝠的样本.
主要成果:
- 与非回声定位的水果蝙蝠 (Pteropodidae) 相比,回声定位蝙蝠通常表现出更简单的板状轮,通常缺乏外围轮和ethmoturbinals.
- 飞类动物表现出更大的嗅觉深处复杂性;一些回声定位器完全没有嗅觉深处.
- 使用鼻声定位的蝙蝠具有独特的轮形态,可能参与呼叫修改.
- 果食蝙蝠,特别是Phyllostomidae中的果食蝙蝠,表现出比其他饮食群体更精致的轮和更大的嗅觉表面积.
结论:

Nose and Nasal Cavity
10.4K
The nose is composed of an observable exterior segment (external nose) and an internal segment within the skull known as the nasal cavity (internal nose). The external nose, visible on the face, consists of a framework of bone and hyaline cartilage enveloped in skin and muscle and lined with a mucous membrane. This structure is supported by the frontal bone, nasal bones, and maxillary bone and is supplemented by a cartilaginous framework comprising the septal nasal cartilage, lateral nasal...

Anatomy of Respiratory System I: Upper Respiratory Tract
4.8K
The upper respiratory tract plays a vital role in the respiratory system, comprising several structures that facilitate air intake and prepare air for the lungs. It also serves as the first line of defense against pathogens and particles. This tract includes the nose and nasal cavity, the oral cavity, the paranasal sinuses, and the pharynx, each with specific functions and features.

Cranial Bones: Lateral View
4.3K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...

Olfactory Receptors: Location and Structure
11.2K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Anatomy of Respiratory System II: Lower Respiratory Tract
3.3K
The lower respiratory tract is anatomically composed of several vital structures, including the larynx, trachea, bronchial tree, alveoli, lungs, and pleurae. Each component has a specific function, and all are intricately connected to ensure efficient respiration.
The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
