背景情况:
- 鼻气道的形状和大小由由头骨神经内置的肌肉调节,包括面部,鼻,阴道和下神经.
- 虽然控制面部,阴道和下神经活动的脑干网络已被理解,但光神经活动 (GPNA) 的排泄模式和起源未被探索.
研究的目的:
- 研究GPNA与其他呼吸道神经相关的排泄模式.
- 探索突突突触相互作用在生成GPNA中的作用.
主要方法:
- 使用在位 perfused脑干制剂 (n=19) 来记录GPNA与 (PNA),面部 (FNA),阴道 (VNA) 和下 (HNA) 神经活动一起.
- 进行了脑干切断 (n=10/19) 来评估突髓突触相互作用对GPNA产生的影响.
主要成果:
- 一般来说,GPNA反映了FNA和HNA排放模式,相对于PNA,它表现出前吸入性活动和强大的吸入性排放.

Cranial Nerves: Types Part II
2.4K
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves. While the first six innervate the head and neck, the latter six nerves innervate the head and neck, as well as organs and tissues in the thoracic and abdominal cavities. They facilitate communication, expression, and autonomic control within the human body.

Olfactory Receptors: Location and Structure
9.2K
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...

Suctioning the Nasopharyngeal Airway
382
Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

Gross Anatomy of the Lungs
1.8K
The lungs are a pair of vital organs connected to the trachea via the left and right bronchi. The base of these organs meets the dome-shaped muscle known as the diaphragm. Encased by the pleurae, the lungs contact the mediastinum. The right lung is shorter yet wider, and has a larger volume than the left lung. The left lung has an indentation known as the cardiac notch. The superior region of the lungs is referred to as the apex, whereas the base is the lower region near the diaphragm. The...

Cranial Part of Parasympathetic Division
1.2K
The cranial part of the parasympathetic division plays a crucial role in regulating the visceral functions of the head and specific structures in the neck, thoracic, and abdominopelvic cavities. Preganglionic fibers of the parasympathetic division exit the brain through cranial nerves III (oculomotor), VII (facial), IX (glossopharyngeal), and X (vagus), delivering parasympathetic output to the respective visceral structures.
