They refer to the two surfaces of the foot; the dorsum (superior surface) and the plantar surface (the sole). The eyes are barely visible through the closed eyelids. This produces a characteristic sign on flexing the elbow a bulge where the muscle belly is, called the Popeye Sign.. The gastrointestinal tract (GI tract, digestive tract, alimentary canal) is the tract or passageway of the digestive system that leads from the mouth to the anus.The GI tract contains all the major organs of the digestive system, in humans and other animals, including the esophagus, stomach, and intestines.Food taken in through the mouth is digested to extract nutrients and absorb The patient would not notice much weakness in the The bones of the skull can be considered as two groups: those of the cranium (which consist of the cranial roof and cranial base) and those of the face. Plus: preparing for the next pandemic and what the future holds for science in China. Teal SI., Moore GW.
Organs of the Thorax Structurally, the nervous system is divided into two parts: Central nervous system consists of the brain and the spinal cord. They are responsible for the fine motor functions of the hand.
Embryology It only has one facet on its head for articulation with its corresponding vertebra (there isnt a thoracic vertebra above it). Haversian canal - the central canal of an osteon (Haversian system) in compact bone, within which blood vessels and nerves travel throughout the bone.
The Hyoid Bone The hyoid bone is a U shaped structure located in the anterior neck.It lies at the base of the mandible (approximately C3), where it acts as a site of attachment for the anterior neck muscles. (1922) Contrib. Aye-ayes use their long, skinny middle fingers to pick their noses, and eat the mucus. ; It then travels inferiorly within the vertebral canal, surrounded by the spinal meninges containing cerebrospinal fluid. In the spring of 2020, we, the members of the editorial board of the American Journal of Surgery, committed to using our collective voices to publicly address and call for action against racism and social injustices in our society. A part of the dorsal ectoderm becomes specified to neural ectoderm neuroectoderm that forms the neural plate along the dorsal side of the embryo. It is comprised of many bones, which are formed by intramembranous ossification, and joined by sutures (fibrous joints).. Consists of a central canal (Haversian canal) surrounded by lamellar bone matrix within which osteocytes reside. It has a relatively simple anatomical course: The spinal cord arises cranially as a continuation of the medulla oblongata (part of the brainstem).
Gastrointestinal tract Hair cell (2017). The thymus gland is located in the superior mediastinum of the thoracic cavity but may also extend into the neck.It is classified as a lymphoid organ, meaning that it plays a role in the development of the immune system. The pinna is larger and such that virtually none of the lumen of the auditory meatus is visible. Embryol., Carnegie Inst. Level of Decussation of the Medial Lemniscus.

It is comprised of many bones, which are formed by intramembranous ossification, and joined by sutures (fibrous joints).. The three germ layers in vertebrates are particularly pronounced; however, all eumetazoans (animals that are sister taxa to the sponges) produce two or three primary germ layers.Some animals, like cnidarians, produce two germ layers (the ectoderm and endoderm) making them diploblastic.
