Muscles of mastication dr abhinand
The muscles of mastication include the temporalis, masseter, medial pterygoid, and lateral pterygoid muscles. These muscles work together to elevate, depress, protrude, and move the mandible sideways during chewing. The temporalis muscle originates on the temporal fossa and inserts on the coronoid process and ramus. The masseter originates on the zygomatic arch and inserts on the ramus and coronoid process. The medial and lateral pterygoid muscles both originate on bones of the skull and insert on the mandible, assisting in elevation, depression and protrusion of the jaw. Dysfunctions of these muscles can cause trismus, myofascial pain
Temporo Mandibular Joint by Dr. Rashi Goel PT
This document provides an overview of the temporomandibular joint (TMJ), including its anatomy, biomechanics, and dysfunction. Specifically, it details the bones, ligaments, muscles, and motions involved in jaw function. The TMJ is described as a tri-joint complex that allows the mandible to open and close for chewing as well as carry out lateral, protrusive, and retrusive movements. Common dysfunctions like bruxism and disc displacement are also mentioned. The purpose seems to be to educate about the structural and functional aspects of the TMJ.
Lower limb muscles attachment
This document lists the bony structures of the pelvis, femur, tibia, fibula, and foot, and their related muscles, ligaments, vessels, and nerves. It provides a comprehensive overview of musculoskeletal attachments and relationships throughout the lower limb.
Muscles of mastication
This document summarizes the muscles of mastication and their innervations. It describes the origin, insertion, action, blood supply and innervation of the four main muscles - medial pterygoid, lateral pterygoid, temporalis and masseter. The medial and lateral pterygoid muscles assist in elevation, protrusion and side to side chewing movements of the mandible. The temporalis elevates the mandible and assists in retraction. The masseter is the strongest elevator of the mandible and also assists in protraction and retraction. All four muscles receive their motor innervation from branches of the mandibular nerve.
Temporomandibular Joint
The temporomandibular joint (TMJ) connects the mandible to the temporal bone. It is a diarthrodial joint that allows for both hinge and gliding movements. The TMJ consists of the condylar process of the mandible, the mandibular fossa of the temporal bone, articular discs, synovial fluid, ligaments including the temporomandibular, sphenomandibular and stylomandibular ligaments, and muscles like the masseter, temporalis, and lateral and medial pterygoid muscles. The muscles of mastication work together to elevate, retract, protrude and move the mandible from side to side for

Thalassemia
Thalassemia for medicine students or anyone interested in the disease.
Thalassemia is a blood disorder passed down through families (inherited) in which the body makes an abnormal form or inadequate amount of hemoglobin. Hemoglobin is the protein in red blood cells that carries oxygen. The disorder results in large numbers of red blood cells being destroyed, which leads to anemia.
A blood disorder involving lower-than-normal amounts of an oxygen-carrying protein.
Thalassemia is an inherited blood disorder characterized by less oxygen-carrying protein (hemoglobin) and fewer red blood cells in the body than normal.
Symptoms include fatigue, weakness, paleness, and slow growth.
Mild forms may not need treatment. Severe forms may require blood transfusions or a donor stem-cell transplant.
The milgram shock experiment
The Milgram experiment was carried out many times whereby Milgram (1965) varied the basic procedure (changed the IV). By doing this Milgram could identify which factors affected obedience (the DV). Obedience was measured by how many participants were shocked to the maximum 450 volts (65% in the original study).
This File contains my perspective of the experiment and gives a better idea about the concept of obedience.

Day 13
During the 13th day of development, primary villi form from cells of the cytotrophoblast that proliferate and penetrate the syncytiotrophoblast. The primary villi are cellular columns surrounded by syncytium. Additionally, cells from the hypoblast migrate along the exocoelomic membrane and form the secondary yolk sac or definitive yolk sac within the original exocoelomic cavity. As the secondary yolk sac forms, portions of the exocoelomic cavity are pinched off to form exocoelomic cysts in the chorionic cavity. The extraembryonic coelom expands and forms the large chorionic cavity, and the extraembryonic mesoderm lining is now referred to
Chemical kinetics
This document discusses key concepts in chemical kinetics including:
1. Chemical kinetics is the branch of chemistry concerned with understanding reaction rates.
2. Factors that affect reaction rates include temperature, pressure, concentration, surface area, and the presence of catalysts.
3. A catalyst lowers the activation energy of a reaction, increasing the reaction rate without being consumed in the process.
Beta oxidation
1. Beta oxidation is the major mechanism of fatty acid oxidation, occurring in the mitochondrial matrix. It removes two-carbon units as acetyl-CoA per cycle.
2. Fatty acids must first be activated through attachment to Coenzyme A before undergoing beta oxidation. The activated fatty acyl-CoA cannot enter the mitochondria on its own and requires the carnitine shuttle system for transport.
3. Each cycle of beta oxidation involves four steps: dehydrogenation, hydration, dehydrogenation, and thiolytic cleavage. This releases acetyl-CoA while shortening the fatty acid chain by two carbons.
