Answer: Perimesencephalic haemorrhage (PSH) is defined as confined bleeding in the cisterns around the mesencephalon, called: the cerebral aqueduct, tegmentum, the tectum, and the cerebral peduncles.
Explanation:
PSH has a probable incidence in patients with negative angiographies of around 50% to 75%. It is a pathology with no predominant age range, reported in all ages in the literature, including childhood. By definition, the condition corresponds to a tomographic finding of blood in the interpeduncular cistern that may extend to the other portions of the mesencephalon. This pathogenesis has not yet been completely clarified, but it is believed to come from a nonarterial source, assuming venous or capillary origin.
<span>Similarities and differences between intramembranous and endochondral ossification<span>
Ossification is the process of bone formation. Intramembranous and endochondral ossification are the two main processes of bone formation that occur during fetal development.
</span>Similarities between intramembranous and endochondral ossification<span>; they turn cartilage into bones during bone formation and they both involve bone cells such as calcium, vascular supply and osteoblasts.
</span>Differences between intramembranous and endochondral ossification<span>; In intramembranous ossification, an intermediate cartilage is not involved, rather the bone tissue is directly laid on a primitive connective tissue called mesenchyma while in endochondral ossification, cartilage is used as a precursor for bone formation. Also, in cases of fractures, the healing process by plaster of Paris occurs through endochondral ossification while fractures which are treated by open reduction and internal fixation are healed by intramembranous ossification.
