Anatomy. The lumbosacral spine and is an important biomechanical region of the body. auditory foramen, external the external acoustic meatus. What exactly is the spine? The spinal cord is situated within the spine. Parasympathetic nerve supply arises through three primary areas: Certain cranial nerves in the cranium, namely the preganglionic parasympathetic nerves (CN III, CN VII, CN IX and CN X) usually arise from specific nuclei in the central nervous system (CNS) and The pelvic cavity opens superiorly to, and is continuous with, the abdominal cavity through the pelvic inlet. Individual vertebrae are named according to In our entire urinary system series, the urinary bladder and Neuron. The urinary bladder and urethra are pelvic urinary organs whose respective functions are to store and expel urine outside of the body in the act of micturition (urination). The spinal column, characteristic of each vertebrate species, [vague] is a moderately flexible series of vertebrae (singular vertebra), each constituting a characteristic irregular bone whose complex structure is composed primarily of bone, and secondarily of hyaline cartilage.They show variation in the proportion contributed by these two tissue types; such variations correlate on CNS stands for central nervous system and includes the brain and spinal cord. All structures and the relationships between them are referenced to the standard anatomical position.In this orientation, the person is considered to be standing upright, with the arms hanging by the side, palms facing forward, and thumbs pointing away from the Step 2: Assignment of Lumbar modifiers (A,B,C) Identify apical lumbar vertebrae (ALV) is the inferior lumbar body that falls outside of the curve The nerves conduct impulses toward or away from the central nervous mechanism. CST is a pseudoscience, and its practice has been characterized as quackery. In humans 12 pairs, the cranial nerves, are attached to the brain, and, as a rule, 31 pairs, the spinal nerves, are attached to the spinal cord. Types: Sensory ganglia: Dorsal root ganglia of spinal nerves and the ganglia of selected cranial nerves. In anatomy and osteology, a foramen (/ f r e m n /; plural foramina, / f r m n / or foramens / f r e m n z /) is an open hole that is present in extant or extinct amniotes.Foramina inside the body of animals typically allow nerves, arteries, veins, or other structures to connect one part of the body with another. An artery (plural arteries) (from Greek (artr) 'windpipe, artery') is a blood vessel in humans and most other animals that takes blood away from the heart to one or more parts of the body (tissues, lungs, brain etc.). This Paper. foramen [fo-ramen] (pl. The two projections at the sides of the sacrum are Inflammation (from Latin: inflammatio) is part of the complex biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants, and is a protective response involving immune cells, blood vessels, and molecular mediators.The function of inflammation is to eliminate the initial cause of cell injury, clear out necrotic cells and tissues damaged from The deep back muscles, also called intrinsic or true back muscles, consist of four layers of muscles: superficial, intermediate, deep and deepest layers.These muscles lie on each side of the vertebral column, deep to the thoracolumbar fascia.They span the entire length of the vertebral column, extending from the cranium to the The backbone encloses the central canal of the spinal cord, which contains cerebrospinal fluid.The brain and spinal cord together make up the central nervous system (CNS). The nerves conduct impulses toward or away from the central nervous mechanism. Our doctors define difficult medical language in easy-to-understand explanations of over 19,000 medical terms. The urinary bladder and urethra are pelvic urinary organs whose respective functions are to store and expel urine outside of the body in the act of micturition (urination). The irregularly shaped bones form the roughly S-shape of the spinal cord. The lumbar vertebrae are, in human anatomy, the five vertebrae between the rib cage and the pelvis.They are the largest segments of the vertebral column and are characterized by the absence of the foramen transversarium within the transverse process (since it is only found in the cervical region) and by the absence of facets on the sides of the body (as found only in the As is the case with most of the pelvic viscera, there are differences between male and female anatomy of the urinary bladder and urethra. The two projections at the sides of the sacrum are The lumbar plexus is a web of nerves (a nervous plexus) in the lumbar region of the body which forms part of the larger lumbosacral plexus.It is formed by the divisions of the first four lumbar nerves (L1-L4) and from contributions of the subcostal nerve (T12), which is the last thoracic nerve.Additionally, the ventral rami of the fourth lumbar nerve pass communicating branches, Types: Sensory ganglia: Dorsal root ganglia of spinal nerves and the ganglia of selected cranial nerves. MedTerms medical dictionary is the medical terminology for MedicineNet.com. This syndrome is characterized by areflexia in the bladder, bowel, and to a lesser degree, lower limbs, whereas the sacral segments occasionally may show preserved reflexes (eg, bulbocavernosus and micturition reflexes). The deep back muscles, also called intrinsic or true back muscles, consist of four layers of muscles: superficial, intermediate, deep and deepest layers.These muscles lie on each side of the vertebral column, deep to the thoracolumbar fascia.They span the entire length of the vertebral column, extending from the cranium to the Conus medullaris syndrome is a sacral cord injury, with or without involvement of the lumbar nerve roots.

PNS stands for peripheral nervous system and includes all nerves outside of the CNS. Definition. In human anatomy, the inferior mesenteric artery, often abbreviated as IMA, is the third main branch of the abdominal aorta and arises at the level of L3, supplying the large intestine from the distal transverse colon to the upper part of the anal canal. The sacrum (plural: sacra or sacrums), in human anatomy, is a large, triangular bone at the base of the spine that forms by the fusing of the sacral vertebrae (S1S5) between ages 18 and 30.. All structures and the relationships between them are referenced to the standard anatomical position.In this orientation, the person is considered to be standing upright, with the arms hanging by the side, palms facing forward, and thumbs pointing away from the The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column (backbone). Action potential The lumbosacral spine and is an important biomechanical region of the body. Individual nerves are made up of thousands of neurons. The spinal cord is a long, thin, tubular structure made up of nervous tissue, which extends from the medulla oblongata in the brainstem to the lumbar region of the vertebral column (backbone). The bony framework of the pelvis is called the pelvic girdle.It is composed of the two hip bones and the sacrum. Triceratops (/ t r a s r t p s / try-SERR--tops; lit. The sacrum situates at the upper, back part of the pelvic cavity, between the two wings of the pelvis.It forms joints with four other bones. In the seated position the lumbosacral discs are loaded three times more than standing. The irregularly shaped bones form the roughly S-shape of the spinal cord.

It is based on fundamental misconceptions about the physiology of the human skull and is promoted as a cure-all for a variety of health conditions. The rib cage, as an enclosure that comprises the ribs, vertebral column and sternum in the thorax of most vertebrates, protects vital organs such as the heart, lungs and great vessels..
