Chapter 41: The spinal cord and meninges Laterally, the pia forms a discontinuous longitudinal septum, the denticulate ligament (see fig. 41-3), which sends about 21 tooth-like processes laterally to fuse with the arachnoid and dura on each side. The ligament is a surgical landmark in that it is attached to the spinal cord about midway between the attachments of dorsal and ventral roots. Further details concerning the spinal cord should be sought in books on neuroanatomy.

Placenta Table 7 - Regions of the Decidua. As the embryo enlarges, the decidua capsularis becomes stretched and smooth. Eventually the decidua capsularis merges with the decidua parietalis, obliterating the uterine cavity. Placental Membrane Function The placental membrane separates maternal blood from fetal blood.

- Cooper's ligament, or the pectineal ligament, is formed from the fascia and periosteum along the superior pubic ramus. A technetium bone scan was performed and demonstrated abnormal uptake about the right superior pubic ramus and the left pubic rami. But the zone of highest von-Mises stress varied during gait from superior pubic ramus for maximum load (Figure 3a) to central inferior ilium for minimum load (Figure 3b).

Glenohumeral ligaments The ligaments may be best seen by opening the capsule at the back of the joint and removing the head of the humerus 1  : One on the medial side of the joint passes from the medial edge of the glenoid cavity to the lower part of the lesser tubercle of the humerus. One on the medial side of the joint passes from the medial edge of the glenoid cavity to the lower part of the lesser tubercle of the humerus. 2  A second at the lower part of the joint extends from the under edge of the glenoid cavity to the under part of the anatomical neck of the humerus.

General Objectives Detailed Objectives. 1. To go over the formation bilaminar embryo, as well as the yolk sac, amniotic cavity, and extraembryonic coelom/chorionic cavity. 2. To be able to recognize the primitive streak and node and other major landmarks, the oropharyngeal and cloacal membranes, allantois, and (later) connecting stalk.t this time cells of the embryo, thought to delaminate from the cytotrophoblast and/or epiblast, contribute the extraembryonic mesoderm, a disorganized layer between the cytotrophoblast and the yolk sac as well as between the cytotrophoblast and the cells surrounding the amniotic cavity (Fig.

Larynx â Ligaments, Membranes, Vocal Cords This first fold is the vestibular fold and it's called the false vocal cord and this second fold forms the true vocal cords and is called the vocal fold. That was the ligaments of the larynx. We've got the extrinsic ligaments which attach the larynx to other structures – so the trachea and the hyoid bone.

- The gingiva appears prominent over the tooth root and may have a slightly concave appearance in the inter-proximal area. • Consistency: Gingiva is generally firm to the touch and attached to the underlying bone and/or tooth. • Surface texture of periodontium: Gingiva may have either a smooth or stippled surface.Stippling is not an indicator of health nor is the absence of stippling an indicator of disease.he special part of the functional epithelium that actually provides the attachment is called the epithelial attachment. This attachment consists of a lamina Lucida, lamina dense, and hemidesmosomes. Connective tissue in periodontium: The predominantly collagenous tissue found beneath the epithelium.

Superficial Features of the Thoracic Wall; Breasts; Anterior Axioappendicular Muscles it spans the superior surface of the sternoclavicular joint and manubrium of the sternum; the combined effect of this ligament, the sternoclavicular ligament and the costoclavicular ligament is to produce a very strong sternoclavicular joint that seldom dislocates.

Ulnar Collateral Ligament Injuries The ligaments around a joint usually combine together to form a joint capsule. A joint capsule is a watertight sac that surrounds a joint and contains. fluid called synovial fluid. In the elbow, two of the most important ligaments are the ulnar collateral ligament (UCL) and the lateral collateral ligament.he ulnar collateral ligament is on the medial (the side of the elbow that's next to the body) side of the elbow, and the lateral collateral is on the outside. The ulnar collateral ligament is a thick band of ligamentous tissue that forms a triangular shape along the medial elbow.

Epiglottis The epiglottis is a flap that is made of elastic cartilage tissue covered with a mucous membrane, attached to the entrance of the larynx. It projects obliquely upwards behind the tongue and the hyoid bone, pointing dorsally.he glossopharyngeal nerve (CN IX) sends fibers to the upper epiglottis that contribute to the afferent limb of the gag reflex. The superior laryngeal branch of the vagus nerve (CN X) sends fibers to the lower epiglottis that contribute to the efferent limb of the cough reflex.

- These minor paired cartilages are seen as nodules in the posterior aryepiglottic folds. The corniculate cartilages attach themselves to the apex of the arytenoid cartilages where the aryepiglottic fold inserts and that is how the nodule-shape in the fold is made.

Sacrotuberous ligament The sacrotuberous ligament is attached by its broad base to the posterior superior iliac spine, the posterior sacroiliac ligaments (with which it is partly blended), to the lower transverse sacral tubercles and the lateral margins of the lower sacrum and upper coccyx.he lower border of the ligament was found to be directly continuous with the tendon of origin of the long head of the Biceps femoris in approximately 50% of subjects. Biceps femoris could therefore act to stabilise the sacroiliac joint via the sacrotuberous ligament.

Placenta As the embryo enlarges, the decidua capsularis becomes stretched and smooth. Eventually the decidua capsularis merges with the decidua parietalis, obliterating the uterine cavity. Placental Membrane Function The placental membrane separates maternal blood from fetal blood.The fetal part of the placenta is known as the chorion. The maternal component of the placenta is known as the decidua basalis.Oxygen and nutrients in the maternal blood in the intervillous spaces diffuse through the walls of the villi and enter the fetal capillaries.he placenta is a fetomaternal organ. The fetal portion of the placenta is known as the villous chorion. The maternal portion is known as the decidua basalis. The two portions are held together by anchoring villi that are anchored to the decidua basalis by the cytotrophoblastic shell.

Alveolar process Structure [edit]. On the maxillae, the alveolar process is a ridge on the inferior surface, and on the mandible it is a ridge on the superior surface. It makes up the thickest part of the maxillae.he alveolar process contains a region of compact bone adjacent to the periodontal ligament (PDL), which is called the lamina dura when viewed on radiographs. It is this part which is attached to the cementum of the roots by the periodontal ligament.
