Macroscopic anatomy, or gross anatomy, is the examination of an animal's body parts using unaided eyesight. Gross anatomy also includes the branch of superficial anatomy. Microscopic anatomy involves the use of optical instruments in the study of the tissues of various structures, known as histology, and also in the study of cells. (Full article...
Called the pericardium, this serous membrane is a two-layered sac that surrounds the entire heart except where blood vessels emerge on the heart's superior side; [4] The pleura is the serous membrane that surrounds the lungs in the pleural cavity; The peritoneum is the serous membrane that surrounds several organs in the abdominopelvic cavity.
Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of surface anatomy. Surface anatomy (also called superficial anatomy and visual anatomy) is the study of the external features of the body of an animal. [1] In birds, this is termed topography.
All of the infrahyoid muscles are innervated by the ansa cervicalis from the cervical plexus (C1-C3) [4] [5] except the thyrohyoid muscle, which is innervated by fibers only from the first cervical spinal nerve travelling with the hypoglossal nerve.
