Spinal cord dr.gosai
The spinal cord extends from the foramen magnum to the L1-L2 vertebrae in adults and the L3 vertebrae in children. It is covered by three meningeal layers - dura mater, arachnoid mater, and pia mater. Cerebrospinal fluid fills the subarachnoid space between the arachnoid mater and pia mater. The spinal cord has gray matter in an H-shape containing nuclei and white matter surrounding it containing ascending and descending tracts. Injuries can cause complete cord section, hemisection with Brown-Sequard syndrome, or other conditions like posterior cord compression or syringomyelia.
Spinal cord injuries
Spinal cord injuries (SCIs) can range from mild concussion to severe laceration or compression of the spinal cord. SCIs are a major health problem, often resulting from motor vehicle accidents. The consequences of SCI depend on the type and level of injury, which are classified as tetraplegia (impairment below the cervical level affecting all four limbs), paraplegia (impairment below the thoracic, lumbar, or sacral regions affecting the trunk and legs), or hemiparalysis (impairment on one side of the body). Clinical manifestations include paralysis, loss of bladder/bowel control, loss of sweating below the neurologic level, and potentially life-threatening respiratory or cardiovascular

Planes of the body
The document discusses the major body cavities and planes of the body. It describes:
1) The thoracic cavity which contains the lungs, heart, esophagus and more. It is surrounded by the pleura, a double-folded membrane.
2) The abdominal cavity which contains the stomach, intestines, spleen, pancreas, liver and more. It is surrounded by the peritoneum, a double-folded membrane.
3) The pelvic cavity which contains the intestines, bladder, urethra and more in females the uterus and vagina.
It also outlines the divisions of the back including the cervical, thoracic, and lumbar regions.
Carotid traiangle
The carotid triangle contains several important structures in the neck. It is bounded by the sternocleidomastoid muscle behind, the posterior belly of the digastric muscle and stylohyoid muscle above, and the omohyoid muscle below. The floor contains muscles like the hyoglossus and thyrohyoid anteriorly and pharyngeal constrictor muscles posteriorly. Within the triangle are the common carotid artery, internal and external carotid arteries and their branches, the internal jugular vein and its tributaries, the vagus, spinal accessory, and hypoglossal cranial nerves, the cervical sympathetic chain, and ansia cervicalis nerve loop. It also contains deep cervical lymph nodes along the internal
Anterior triangle of neck
The document describes the anatomy of the anterior triangle of the neck, which contains three smaller triangles - the submental, digastric, and carotid triangles. The submental triangle is bounded by the symphysis menti above, the body of the hyoid bone below, and the anterior bellies of the digastric muscles on each side. It contains submental lymph nodes and vessels. The digastric triangle is bounded above by the lower border of the mandible, below and in front by the anterior belly of the digastric muscle, and below and behind by the posterior belly. It contains the submandibular gland, part of the parotid gland, and submandibular lymph nodes.
Head and neck anatomy 4 the neck
The document discusses the anatomy of the neck region. It describes the neck as being bounded by the mandible above and clavicle below, and divided into four compartments - visceral, vertebral, and two vascular compartments. The neck contains many structures including blood vessels, nerves, lymph nodes, the thyroid and parathyroid glands, and parts of the respiratory and digestive systems. The neck is further divided into triangles by the sternocleidomastoid muscle, which helps to organize the various structures contained within the neck.
Spinal cord
The spinal cord runs through the vertebral canal and extends from the foramen magnum to the L2 vertebra. It gives rise to 31 pairs of spinal nerves and has cervical, thoracic, lumbar, sacral and coccygeal regions. The meninges that surround it include the dura mater, arachnoid mater and pia mater. The spinal cord has gray matter containing neuron cell bodies and white matter containing myelinated axons. Descending motor pathways control voluntary movement while ascending sensory pathways transmit proprioceptive and discriminative touch information to the brain.
Diaphragm
The diaphragm is a dome shaped muscle that forms the partition between the thoracic and abdominal cavities. It has three parts that arise from the sternum, ribs, and lumbar vertebrae. Its central tendon inserts below the pericardium in a trilobar shape. The diaphragm receives motor innervation from the phrenic nerve and sensory innervation from lower thoracic nerves. During respiration, the diaphragm contracts to increase the volume of the thoracic cavity.
Body cavities
The document discusses the major body cavities in humans. There are two main cavities - the dorsal cavity which protects the nervous system and is divided into the cranial cavity housing the brain and vertebral cavity housing the spinal cord, and the ventral cavity which houses the internal organs. The ventral cavity is further divided into the thoracic cavity containing the lungs, heart and other thoracic organs, and the abdominopelvic cavity containing the stomach, intestines, and other abdominal and pelvic organs. The document also briefly mentions other body cavities like the oral, nasal, orbital, middle ear and synovial cavities.
Spinal cord
This document describes the structure and function of the spinal cord. It discusses the external and internal anatomy, including the protective meninges, enlargements in the cervical and lumbar regions, conus medullaris, cauda equina, and filum terminale. Internally, it describes the gray matter, white matter, tracts, and roots. The spinal cord acts as a pathway for sensory and motor impulses and is responsible for reflexes. Ascending tracts conduct sensory information to the brain and descending tracts carry motor commands from the brain.

Surgical interventions on the spinal cord are considered important in various medical conditions that affect the spinal column and its associated structures. The spinal cord is a vital part of the central nervous system, responsible for transmitting signals between the brain and the rest of the body. Surgical procedures on the spinal cord are performed to address a range of issues, including injuries, tumors, degenerative conditions, and congenital abnormalities. Given the complexity and sensitivity of the spinal cord, surgical interventions require specialized expertise and careful consideration.
Dr bikal paraplegia
1. Paraplegia refers to weakness or paralysis of both legs, which is most often caused by diseases of the thoracic spinal cord, cauda equina, or peripheral nerves.
2. Spastic paraplegia involves increased muscle tone and weakness due to upper motor neuron lesions, while flaccid paraplegia presents with decreased muscle tone and weakness from lower motor neuron lesions.
3. The key distinguishing features between the two types are muscle tone (increased in spastic vs decreased in flaccid) and deep tendon reflexes (exaggerated in spastic vs absent in flaccid).
Neck triangles anatomy
The document describes the anatomy of the anterior and posterior triangles of the neck. It details the bones, muscles, blood vessels, nerves and other structures found in each triangle. Key structures mentioned include the cervical vertebrae, carotid artery, thyroid gland, larynx, and various nerves such as the hypoglossal and recurrent laryngeal nerves. The triangles described are the submandibular, submental and carotid triangles located in the anterior neck region.
Trigeminal Nociceptive Facilitation
The trigeminal nerve is responsible for sensory innervation of the face and front parts of the head. It has three main branches that enter the skull through different openings and relay sensory information to the trigeminal ganglion and trigeminal nucleus in the brainstem. The trigeminal nucleus is a collection of nerve cells that receives all sensory information from the face, including touch, pain, and temperature. It contains a detailed map of the face and relates this sensory input to different areas of the brain. Disturbances in trigeminal nerve function can lead to pain conditions like trigeminal neuralgia.

Fiber bundles with a common function are called tracts. The document discusses several ascending and descending tracts in the spinal cord, including:
- The posterior column-medial lemniscus pathway, which carries sensations of discriminative touch, vibration, and conscious proprioception to the thalamus and cerebral cortex.
- The spinothalamic tract, which carries sensations of pain, temperature, and light touch to the thalamus and diffuse cortical regions via the spinal lemniscus.
- Shorter tracts within the spinal cord that connect segments and carry proprioceptive information to complete reflex arcs or to the brainstem and cerebellum for motor coordination.
Trigeminal nerve ppt
The trigeminal nerve is the largest of the cranial nerves. It has both sensory and motor components. It originates from four nuclei in the brainstem and exits the skull through three divisions - ophthalmic, maxillary, and mandibular. The ophthalmic division innervates parts of the face, eye, and nasal cavity. The maxillary division innervates parts of the face, nasal cavity, and palate. The mandibular division innervates muscles of mastication and parts of the face.
Surgical anatomy of the neck
This document provides an overview of the surgical anatomy of the neck, including:
1. The developmental anatomy of the neck structures derived from the pharyngeal arches.
2. The surface anatomy landmarks of the neck that can be palpated, including bones, muscles, vessels and glands.
3. The fascial layers of the neck, including the superficial cervical fascia, and three layers of the deep cervical fascia - the superficial investing layer, carotid sheath, and deep prevertebral layer.
4. The triangles used to compartmentalize the neck structures, including the anterior, posterior, and other subdivisions.
Anatomy of spine for spinal anaesthesia
The vertebral column consists of 33 vertebrae that provide structural support, protect the spinal cord, and allow mobility. Each vertebra is composed of a vertebral body, processes, and joints that connect to adjacent vertebrae. The spinal cord runs through the vertebral column and is segmented into cervical, thoracic, lumbar, sacral and coccygeal regions. Surrounding structures include the ligaments, discs, dura mater, arachnoid mater, pia mater, epidural space, and subarachnoid space. Knowledge of the vertebral column's anatomy is essential for performing spinal and epidural procedures safely and effectively.
Anatomy and blood supply of spinal cord
The spinal cord extends from the foramen magnum to the L1-L2 vertebral level in adults. It is protected by vertebrae and surrounded by three meninges. It has cervical, thoracic, lumbar, and sacral regions. It contains ascending and descending tracts that transmit sensory and motor signals. The anterior spinal artery supplies the anterior two-thirds and segmental arteries also contribute.
NECK anatomy muscles with clinical anatomy.pdf
The document discusses the clinical anatomy of the neck. It begins by describing the structures located in the neck that allow for thinking, speaking, seeing, hearing, tasting, and smelling. It then discusses the cervical spine, fascial compartments of the neck including the carotid sheath, tissue spaces of the neck including the prevertebral space, and triangles of the neck including the anterior and posterior triangles. It also summarizes key structures in the neck including the thyroid gland, larynx, pharynx, trachea, great vessels, and cervical sympathetic trunk.
Radiological anatomy of_temporal_bone[1]
The document describes the anatomical structures of the temporal bone, including its four parts - squamous, mastoid, petrous, and tympanic. It details the locations and structures of the mastoid process, styloid process, zygomatic process, external acoustic meatus, middle ear cavity, mastoid antrum, ossicles, inner ear, internal auditory canal, carotid canal, jugular foramen and fossa, and course of the facial nerve. CT and MRI are described as the main imaging techniques used to evaluate the temporal bone, with CT excellent for osseous structures and MRI better for soft tissues.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.Recently uploaded (20)
