In Human Anatomy, Hyoid is a U-shaped bone present in the ventral aspect of neck at the level of fourth cervical vertebra. It is a small bone placed between the root of tongue and the thyroid cartilage. Hyoid bone represents a link be- tween the head and neck. Although located in the neck, hyoid bone be- cause of its brachial origin belongs to the visceral skeleton(1). This bone is over stilohyoid ligament (ligamentum stylohyoideum) stilohyoid muscle (mus- culus stylohyoideus) and last digastric abdominal muscle (posterior venter musculi digastrici) related to the base of the skull, through geniohyoid muscle (musculus geniohyoideus) milohyoid mus- cle (musculus mylohyoideus) and anterior digas- tric muscle belly (venter anterior musculi digastrici)
Carpal tunnel syndrome (CTS) is a common painful disorder of the wrist and hand. Pain or other symptoms (numbness, tingling, and weakness) arise as the median nerve is compressed (3). The cause is not always found to be within the carpal tunnel (4). Compression
The nervous system consists of two divisions; the central nervous system and the peripheral nervous system. The central nervous system is the combination of the nerves within the skull and spine, while the peripheral nervous system is the nervous system that goes everywhere inside (autonomic nervous system) and outside (somatic nervous system) around the body except skull and spine. The somatic nervous system has two kinds of nerves; afferent nerves that carry sensory signals from the external parts of the body to center, and efferent nerves which carry motor signals from central nervous system to muscular system. The autonomic nervous system also has afferent and efferent nerves and afferent nerves carry sensory signals from internal organs
The cut on Nicole 's throat was so deep that it nicked her vertebra C3, the portion of the spine that supports the neck. Her windpipe and larynx were clearly seen, and the 2 carotid arteries severed, along with 1 jugular artery and the other jugular cut and left dangling by a thread. The windpipe and larynx consists of several muscles and cartilage. It is difficult to even begin to tear cartilage due to its flexibility, stiffness, and rigidity. In order to have cut through the windpipe, it would have been difficult enough.
BACKGROUND AND LITERATURE REVIEW 2. Clinical Background 2.1 The human spine The human spine (also referred to as vertebral column or spinal column) is a bony structure in the middle of the back starts at the base of the skull and continues to the pelvis. It consists of vertebrae (small bones) and joints (intervertebral disks) together to form a flexible and stable spinal column. The spinal cord and nerve roots are preserved by the vertebral body, supports the body and responsible for carrying weight. The disks allow movement in the spine and have a shock absorbing.
PREVALENCE AND INCIDENCE Spasticity affects more than an estimated 12 million people worldwide. 1.3. OTHER CONDITIONS THAT MAY CAUSE SPASTICITY INCLUDE Traumatic brain injury (TBI) Spinal cord injury (SCI) Brain damage due to a lack of oxygen Stroke Encephalitis Meningitis
The narrow gap between the anterior crux of helix and tragus is deficient of cartilage and comprises of dense fibrous tissue, known as incisura terminalis. This serves as a site for endaural incision to access the temporal bone. (21,22) External Auditory
Stratum Lucidum Stratum lucidum consists of flattened epithelial cells. Most of the cells have degenerated nucleus and in some the nucleus is completely absent. This layer is present only in the thick skin of areas such as the fingertips, palms and soles. It consist of four to six layers of flattened clear, dead keratinocytes that contains large amount of keratin and thickened plasma membrane. This provides an additional level of toughness in this region of thick skin.
Jugular notch - the superior border of the manubrium 2. Sternal body - the central portion of the sternum 3. Xiphoid process - the inferior, pointy process on the sternum 4. Forth costal cartilage-the cartilaginous articulation between 4th rib and manubrium 5. Acromion-the postro-lateral boney projection of the scapula 6.
This third type can result in complete paralysis, along with bowel or bladder dysfunction. What happens with this type, is that the spinal luid and meninges stick out through an unusual vertebral opening. The last type, and most severe type of spina bifida is called Myelomeningocele. What happens with this type is that there is an opening of the spine, where the spinal cord and all of the neural elements get exposed. With this type, people can be partially paralyzed in the body parts that are below the spinal cord opening.
This syndrome is caused by damage inflicted to the anterior aspect of the spinal cord or as a result of decreased vascular supply. Brown-Sequard syndrome occurs in the presence of damage to one side of the spinal cord more so than the other, resulting in ipsilateral loss of motor function and sensory loss too. Posterior cord syndrome is very rare and the cause is most commonly found with chronic myelopathy resulting in loss of vibration and proprioception below the level of
The hypothalamus communicates to each lobe differently. The hypothalamo-hypophyseal tract system is the specific way the hypothalamus communicates with the posterior lobe of the pituitary gland. It is a nervous system connection with direct connecting neurons. The neurons are located in the hypothalamus and then axons extend down to the posterior lobe of the pituitary gland. The neurons produce hormones that slide down the axons and end up in the posterior lobe.
Morrie Schwartz was diagnosed by a frightening sickness known as ALS. ALS (amyotrophic lateral sclerosis) is an exceptionally uncommon sickness inside of your sensory system that debilitates muscles and affects the physical capacity. Morrie Schwartz had been determined to have ALS and his previous understudy, Mitch, revived their kinship through his condition. The illness is known as an motor neuron infection that is portrayed by the steady degeneration and demise of motor neurons. Motor neurons are nerve cells a portion of a pathway that send driving forces to the cerebrum and the spinal rope.
