Document Summary

*heart is on left side -> left lung is smaller. Pleural cavities: lung surrounded by a serous membrane - pleura, parietal layer - outside layer, doesn"t touch lung, visceral layer - touches lung, pleural cavity, pleural fluid. Pneumothorax: collapsed lung, accumulation of air in pleural cavity, pressure around lung (cannot expand, symptoms: chest pain, labored breathing, treatment (depends on severity) - wait for absorption, insertion of tube to remove air. Lecture #17 - respiratory system: pharynx, larynx, trachea, bronchi (1, 2, 3, large bronchioles. Small bronchioles: terminal bronchioles, no cartilage, smooth muscle. Give rise to alveolar sacs & alveoli asthma. Alveoli: respiratory bronchioles lead into alveolar ducts, alveolar ducts lead to alveolar sacs made up of alveoli (bunches of grapes, thin walls for gas exchange, capillaries between alveoli, large surface area ~ size of tennis court. Lecture #17 - respiratory system pneumocyte type i. Vein = to the heart: pulmonary artery (2)

1: Facelift Anatomy

With age, characteristic changes occur in the central third of the face. ^[¹^] A youthful midface is characterized by prominent cheeks and a smooth transition between the lower eyelid and cheek. Structural, soft tissue, and skin changes develop as wrinkles and creases, progressive ptosis, and general atrophy of the structures.

Pessa confirmed the changes seen in the bony structures of the face, and these include a downward migration of cephalometric points. ^[²^] The downward migration manifests as a change in soft tissue volume. The effects of gravity and repeated animation of the face also directly affect the soft tissue that overlies the mimetic musculature.

The results of magnetic resonance imaging (MRI) evaluations have helped to determine that the mimetic muscles themselves remain intact; however, the attachment to the overlying soft tissue and skin changes. The repeated action of smiling results in deepening of the nasolabial fold at the point at which the superficial musculoaponeurotic system (SMAS) inserts into the dermis.

2: Pancreas Anatomy

Embryology

The pancreas develops as 2 buds (outpouchings) of endoderm from the primitive duodenum at the junction of the foregut and the midgut. A small ventral bud (pouch) forms the lower (inferior) part of the head and the uncinate process of pancreas, whereas a large dorsal bud (pouch) forms the upper (0) part of the head as well as the body and tail of the pancreas. The ventral bud rotates behind the duodenum dorsally from right to left and fuses with the dorsal bud, and the duct of the distal part (body and tail) of the dorsal bud unites with the duct of the ventral bud to form the main pancreatic duct (of Wirsung). Because the common bile duct (CBD) also arises from the ventral bud, it forms a common channel with the main pancreatic duct. The remaining proximal part (head) of the duct of the dorsal bud remains as the accessory pancreatic duct (of Santorini).

3: Conduction System of the Heart

The conducting system of the heart consists of cardiac muscle cells and conducting fibers (not nervous tissue) that are specialized for initiating impulses and conducting them rapidly through the heart (see the image below). They initiate the normal cardiac cycle and coordinate the contractions of cardiac chambers. Both atria contract together, as do the ventricles, but atrial contraction occurs first.

The conducting system provides the heart its automatic rhythmic beat. For the heart to pump efficiently and the systemic and pulmonary circulations to operate in synchrony, the events in the cardiac cycle must be coordinated.

4:Spleen Anatomy

Overview

The spleen is an organ shaped like a shoe that lies relative to the 9th and 11th ribs and is located in the left hypochondrium and partly in the epigastrium. Thus, the spleen is situated between the fundus of the stomach and the diaphragm. The spleen is very vascular and reddish purple in color; its size and weight vary. A healthy spleen is not palpable.

Development

The spleen develops in the cephalic part of dorsal mesogastrium (from its left layer; during the sixth week of intrauterine life) into a number of nodules that fuse and form a lobulated spleen. Notching of the superior border of the adult spleen is evidence of its multiple origin (see the image below)
