Abstract

Bu çalışmada 1 adet erişkin vaşağın (Lynx lynx) larynx, trachea ve akciğerleri incelendi. Diseksiyon ve ölçümlerle larynx kıkırdakları, trachea ve akciğerlerin makroanatomik ve histolojik yapısı ortaya konulmaya çalışıldı. Trachea’nın bifurcatio trachealis’e kadar, çapları akciğerlere doğru yaklaştıkça daralan, 48 adet kıkırdak halkaya (cartilago trachealis) sahip olduğu tespit edildi. Toplam trachea uzunluğu 172.36 mm idi. Vaşak trachea’sının enine kesitinin daireye benzediği görüldü. Vaşak akciğerindeki pulmo sinister lobus cranialis ve lobus caudalis adında iki ana loptan oluşuyordu. Pulmo sinister’in lobus cranialis’i de kendi arasında pars cranialis ve pars caudalis olarak bölünmüştü. Pulmo dexter lobus cranialis, lobus medius, lobus accessorius ve lobus caudalis olmak üzere dört ana loptan oluşmaktaydı. Trachea’yı dışarıdan saran hiyalin kıkırdak yapısı belirlendi. Bu kıkırdağın açık olan uçlarını kapatan ve kıkırdağı dışardan saran musculus transversus trachea adlı kas yapısı tespit edildi. Trachea’nın tunika mukoza, submukoza, tunika adventisya katmanlarından oluştuğu belirlendi. Akciğeri dıştan saran bağ doku kapsülü, respiratuvar bronşiol sonları, alveoller, intraalveoler septum ve bol miktarda kan damarlarının bulunduğu tespit edildi. İntraalveolar septumlarda; kapillar damarlar, eritrositler belirlendi. Alveol yüzeyini kaplayan tip I ve tip II pnömositler görüldü. Ayrıca alveoler keselerde makrofajların olduğu belirlendi.

Macro Anatomical and Histological Study of Larynx Cartilage, Trachea, and Lungs in Lynx (Lynx lynx)

Abstract

In this study the larynx, trachea, and lungs of one 1.5-year-old adult female lynx (Lynx lynx) were examined. The macro anatomical and histological structure of the larynx cartilages, trachea, and lungs were tried to be revealed by dissection and measurements. It was determined that the trachea had 48 cartilage rings (cartilago trachealis) up to the bifurcatio trachealis, the diameters of which narrow as they approach the lungs. The total tracheal length was 172.36 mm. It was seen that the cross-section of the lynx trachea resembled a circle. The hyaline cartilage structure surrounding the trachea was determined. A muscle structure called musculus transversus trachea, which closes the open ends of this cartilage and surrounds the cartilage from the outside, was detected. It was determined that the trachea consisted of tunica mucosa, submucosa, and tunica adventitia layers. The pulmo sinister in the lynx lung consisted of two main lobes, lobus cranialis, and lobus caudalis. Lobus cranialis was also divided among itself as pars cranialis and pars caudalis. Pulmo dexter was divided into four main lobes as lobus cranialis, lobus medius, lobus caudalis, and lobus accessorius. It was determined that there was connective tissue capsule surrounding the lung, respiratory bronchioles, alveoli, intraalveolar septum, and abundant blood vessels. In intraalveolar septum; capillaries, erythrocytes were determined. Type I and type II pneumocytes were seen covering the alveolar surface. In addition, it was determined that there were macrophages in the alveolar sacs.
