Estudamos em 30 corações de Bos taurus adultos, fêmeas da raça Canchim, as relações entre a parede arterial e o tecido circunjacente nos diferentes segmentos pontinos. Para o estudo microscópico foram coletados fragmentos de material a fresco tratados segundo técnicas microscópicas convencionais. As fibras musculares dos segmentos pré-pontino e pós-pontino são de localização subepicárdica. As fibras musculares estriadas cardíacas do segmento pontino apresentam-se predominantemente oblíquas ao vaso, acompanhando o seu eixo longitudinal; separam-se para formar um espaço losângico que abriga no centro a referida artéria e nas laterais tecido conjuntivo, constituído por fibras colágenas, elásticas, vasos, nervos e tecido adiposo.
اظهر المزيد [+] اقل [-]Thirty hearts of female Bos taurus bovines of Canchin breed were studied, the relationship between the arterial wall and the tissues surrounding different drawbridge segments was also assessed. Tissue fragments were collected and treated according to conventional microscopic techniques. Muscle fibers of the pre-bridge and post-bridge segments were of subepicardiac in location. The striate cardiac muscle fibers of the bridging segment are predominantly oblique to the vase, accompanying its longitudinal axis; they separate themselves to form a losanged space to shelter in its center the coronary artery and at its laterals the conjunctive tissue, constituted by colagens and elastic fibers, vases, nerves and adipose tissue
