Foramina of the skull Essays

The Spine: Composed of 33 vertebrae, the spine consists of 7 cervical, 12 thoracic, 5 lumbar, 5 fused sacral and 4 fused coccygeal vertebrae. The width of the vertebral bodies generally increases craniocaudally, except at T1-T3. The normal curve of spine includes: 1. Cervical lordosis (20-400) 2. Thoracic kyphosis (20-400), 3. Lumbar lordosis (30-500) and 4. Sacral kyphosis (not more than 400). ANATOMICAL PLANES:  Coronal or frontal plane: It is a vertical imaginary line which divides the

It’s contributes to the multiple regions of the skull: anterior cranial fossa, middle cranial fossa, pterygopalatine fossa, infratemporal roof, , orbit, lateral wall of the cranial vault and roof and lateral wall of the nasal cavity, It’s articulates with the following bones: The ethmoid bone, the

he later called the Primary Respiratory Mechanism (PRM). In 1900, G.Sutherland then found the school of Cranial Osteopathy (Brooks, 2000). Sutherland then began to study in specific the bony articulations of the skull which he described as the “cranial bowl”, offering the premise that Articular mobility at the cranial base was attributed to the cartilaginous origin of the bones. The “interossous membrane” unites the cranial bones and the sacrum; therefore he believed that if any part of the system

Cranial nerve damage Ten pairs of cranial nerves originate in the brain stem continuing to different areas of the face and body. Two pairs of cranial nerves originate in the cerebrum. Cranial nerves travel through specialized holes (foramina) in the skull originated for this purpose. The Abducens nerve offers the precise control needed for specialized movements such as the blink of an eye to a smile resulting from a scant upturning of a lip made possible by the Facial nerve. Damage to any of

Hind brain (Rhombincephalan) the hind brain contain the brain stem and the medulla oblongata (Myelencephalon) form by the anterior thickening of basal plate and posterior alar plate separated by sulcus in the fourth ventricle. The hind brain continues to form the spinal cord. As like cerebrum, cerebellum has fissured mass in the posterior cranial fossa attached with brain stem by three pairs of peduncles. From the base of the brain stem the 12 pairs of cranial nerves are arising. The motor nuclei

Contextual project Texila American University SCHOOL OF NURSING Block-1 ABHILASH P.M APPLICATION NUMBER: 17737 RN-BSN Neurological System & Mental Status Assessment Introduction: The neurological exam should be incorporated into the rest of your physical exam. Although it can be intimidating to those just learning it and although it will inevitably take you a long time to do at first, practice will certainly allow you to become proficient. Your job at this stage is to work on accuracy and thoroughness

Anatomy of the Lacrimal System Study of the lacrimal system is a synthesis of two disciplines, ophthalmology and otorhinolaryngology, which work closely together in the treatment of nasolacrimal disorders. A thorough understanding of the anatomy of the lacrimal system will help the surgeon to reach correct diagnosis, facilitate the chance of a successful surgical outcome and makes the surgeon confident of his skills. The lacrimal drainage system anatomy can be discussed under following components:

order to better serve clients. There are twelve pairs of cranial nerves. Each pair has a name and a Roman numeral assigned to it. These nerves are developed in utero during gestation. These nerves leave the brain and pass through the foramina of the skull in order to travel to the sensory organs or to the muscles of the head and neck that they innervate. Cranial nerves may serve motor functions, sensory functions, or both. All cranial nerves serve some relation to the processes of speech, language

induction, as discovered by Michael Faraday in 1838. If a pulse of current passing through a coil placed over a person’s head has sufficient strength and short enough duration, rapidly changing magnetic pulses are generated that penetrate scalp and skull to reach the brain with negligible attenuation. These pulses induce a secondary ionic current in the brain. The site of stimulation of a nerve fibre is the point along its length at which sufficient current to cause depolarisation passes through its
