LECTURE #12

The extensive chapter covers the major bones of the skeleton as well as their associated muscles and tendons. Blood suppfy and inner-vation are reviewed for each muscle group. Bones of the skull may be classified as belonging to the neurocranium (the portion of the skull that surrounds and protects the brain) or the viscerocranium (ie, the skeleton of the face). Osteology: bones of the neurocranium: Frontal, Parietal, Temporal, Occipital, Ethmoid, Sphenoid.

Bones of the viscerocranium (surface): Maxilla, Nasal, Zygomatic, Mandible. Bones of the viscerocranium (deep): Ethmoid, Sphenoid, Vomer, Lacrimal, Palatine, Inferior nasal concha Articulations: Most skull bones meet at immovable joints called sutures. The sole exception is the temporomandibular joint, a synovial joint that has a hinge-gliding movement. The coronal suture is between the frontal and the parietal bones. The sagittal suture is between two parietal bones. The lambdoid suture is between the parietal and the occipital bones. The bregma is the point at which the coronal suture intersects the sagittal suture and is the site of the anterior fontanelle in an infant.

The lambda is the point at which the sagittal suture intersects the lambdoid suture and is the site of the posterior fontanelle in an infant. The pterion is the point on the lateral aspect of the skull where the greater wing of the sphenoid, parietal, frontal, and temporal converge bones. The temporomandibular joint is between the mandibular fossa of the temporal bone and the condylar process of the mandible.

The parotid gland is the largest of the salivary glands and has a dense connective capsule tissue. Structures found within the substance of this gland include the following: Motor branches of the facial nerve. CN VII enters the parotid gland after emerging from the stylomastoid foramen at the base of the skull. Superficial temporal artery and vein. The artery is a terminal branch of the external carotid artery.

External carotid artery: Retromandibular vein, which is formed from the maxillary and superficial temporal veins.

FACE: The muscles of facial expression are derived from the second pharyngeal arch and are supplied by motor branches of CN VII Table 2.

Great auricular nerve, which is a cutaneous branch of the cervical plexus. Auriculotemporal nerve, which is a sensory branch of V3. It supplies the TMJ and conveys postganglionic parasympathetic fibers from the otic ganglion to the parotid gland. Parotid (Stensen's) duct, which enters the oral cavity at the level of the maxillary second molar. The facial artery is a branch of the external carotid artery in the neck. It terminates as the angular artery near the bridge of the nose. The facial vein parallels the course of the facial artery. It terminates by joining the anterior branch.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New ways of liver regeneration have been found 22.10.2023

Researchers in the United Arab Emirates have discovered innovative ways to restore the liver. Foreign sources report on epigenetics methods that can promote the regeneration of this important organ of the human body.

World scientists have long been looking for unknown ways to renew the cells of human internal organs. An important discovery in this area was made by a team of specialists from the UAE.

According to the researchers, an effective way to stimulate liver regeneration is to remove certain parts of the epigenome responsible for suppressing jumping genes. This method results in a redistribution of epigenetic marks.

This is explained by the fact that a form of epigenetic compensation prevents the activation of transposable elements of the genome. It blocks the regulation of gene expression by compensatory epigenetic marks. This process ensures that repressive genes are activated earlier, which helps support regeneration after surgical removal of parts of the liver, as is often the case with tumor resection.

The results open the way to a deeper understanding of liver regeneration and the unique ability of this organ to recover, which exists in all mammalian species, including humans. In laboratory experiments, deletion of the core epigenetic regulator UHRF1 in the liver of mice led to a milder response of other particles, and the organ itself was successfully restored by activating specific genes.
