The scalp is the soft tissue covering the skull. It consists of 5 layers - skin, connective tissue, the epicranial aponeurosis, loose connective tissue, and the pericranium. The occipitofrontalis muscle is found within the scalp and has frontal and occipital bellies which are innervated by branches of the facial nerve. This muscle allows movement of the scalp. Arterial blood supply comes from branches of the external carotid artery including the superficial temporal artery. Sensory innervation is provided by branches of the trigeminal nerve and cervical nerves while motor innervation comes from the facial nerve. Wounds of the scalp bleed profusely
Dural folds and cavernous sinus
The document summarizes key anatomical structures related to the dura mater and cavernous sinus. It describes the layers of the meninges and identifies four dural folds - the falx cerebri, tentorium cerebelli, falx cerebelli, and diaphragma sella. It also details the location, relations, tributaries, and communications of the cavernous sinus.
Anatomy of the Scalp
The scalp is made up of 5 layers - skin, dense connective tissue, aponeurotic layer, loose connective tissue, and pericranium. It is supplied by branches of the internal and external carotid arteries and drains venously into the superficial temporal and posterior auricular veins. The scalp is innervated by branches of the trigeminal and cervical nerves and drains lymphatically to occipital, mastoid, pre-auricular and parotid lymph nodes.
Layers of the Scalp.pptx
The scalp has 5 layers - skin, connective tissue, aponeurosis, loose connective tissue, and periosteum. It receives a rich blood supply from branches of the external carotid artery and ophthalmic artery. Veins drain the scalp into the angular, retromandibular, and occipital veins. Lymphatics drain to occipital, mastoid, preauricular, and submandibular nodes. The scalp is innervated by the trigeminal nerve anterior to the ears and cervical nerves C2 and C3 posterior to the ears.
Brainstem
The document provides information about the brainstem, which consists of the medulla, pons, and midbrain. It describes the gross anatomy and internal features of the medulla, including nuclei, tracts, and blood supply. Specific conditions that can affect the medulla, such as raised intracranial pressure and lateral/medial medullary syndromes, are also discussed. The pons is then covered, outlining its anterior and posterior surfaces, nuclei including the pontine nuclei, and blood supply from the basilar artery.
Neck dissections
This document discusses the history and anatomy of neck dissections for head and neck cancer. It traces developments from the late 19th century of increasingly conservative neck dissections to preserve important structures. It describes the levels and boundaries of lymph node groups involved in the neck dissection staging system, including levels I-V. Key structures like the hypoglossal nerve and spinal accessory nerve are discussed in relation to the lymph node groups.
719_Pectoral_Region.pptx
This document provides information about the muscles of the pectoral region, including the pectoralis major, pectoralis minor, serratus anterior, and subclavius. It describes the origin, insertion, innervation, and actions of each muscle. It also discusses the blood and nerve supply to the pectoral region, as well as the clinical relevance of structures like the clavipectoral fascia. Understanding the muscles of the pectoral region is important for identifying and describing them, and knowing their actions and clinical applications.
Musculoskeletal Anatomy: Lesson 3. Neck.pptx
Different musculoskeletal structures of the Neck that includes the bones, muscles, ligamanents, nerves, and blood vessels present in the neck area
HEAD AND NECK 23.pdf
The document discusses anatomical structures of the head and neck region, including bones, fasciae, muscles, blood vessels, and nerves. It notes the locations of important structures such as the hyoid bone at the C3 level and the cricoid cartilage terminating at the C6 level. It describes the cervical triangles formed by the sternocleidomastoid muscle and subdivided by other structures. Finally, it summarizes the branches and innervation of the cervical plexus, including cutaneous, muscular, and communicating branches.
Regional anaesthesia strategies for upper limb surgeries
This document provides an overview of regional strategies for upper limb surgeries. It begins with an introduction to brachial plexus anatomy and dermatomal, muscular and osteotomal supply to the clavicle, shoulder, upper arm, elbow, forearm and hand. For each region, relevant surgical approaches and recommended regional anesthesia techniques are described, such as interscalene block for shoulder/upper arm surgeries and axillary block for forearm procedures. The document aims to guide anesthesia providers in selecting the appropriate nerve block based on the specific limb location being operated.
Suboccipital region and muscles of back
This document provides information about muscles in the back and suboccipital region. It begins with multiple choice questions then provides details about:
- Muscles of the back including the superficial group (trapezius, levator scapulae) and deep group (erector spinae, semispinalis, suboccipital muscles)
- Structures in the suboccipital region such as the suboccipital triangle bounded by the atlas, occiput and mastoid process
- Nerves that supply muscles including the suboccipital nerve, a branch of C1
- Procedures like cistern puncture that are done through the suboccipital triangle
Scalp Anatomy
The scalp has five layers - skin, deep connective tissue, aponeurosis, loose connective tissue, and periosteum. It is innervated by branches of the trigeminal nerve and cervical nerves and supplied by branches of the external carotid and ophthalmic arteries. The occipitofrontalis muscle allows movement and raising of the eyebrows. Lymph drains from the scalp to occipital, cervical, mastoid, parotid, preauricular, and submandibular lymph nodes.
Orbital anatomy
This document provides an overview of orbital and ocular anatomy. It describes the bones that make up the orbit, including the frontal, zygomatic, maxillary, ethmoidal, sphenoid, lacrimal and palatine bones. It details the structures within the orbit, including the extraocular muscles, optic nerve, blood vessels and cranial nerves involved in vision. The anatomy of the eyeball is also summarized, including the cornea, as well as the pathways of the visual system from the retina to the visual cortex.
1 The scalp.pptx
The scalp consists of five layers - skin, connective tissue, aponeurosis, loose areolar tissue, and pericranium. The scalp receives its blood supply from branches of the external and internal carotid arteries. It drains venously into the facial, superficial temporal, external jugular and occipital veins. Lymph from the scalp drains to submandibular, parotid, mastoid and occipital lymph nodes. The occipitofrontalis muscle connects the occipital bone to the eyebrows and allows movement of the scalp. Injuries to the scalp often bleed severely due to the rich vascular supply.
Head and neck anatomy
a very short and concise head and neck anatomy presentation; an overview of head and neck anatomy prepared for a mixed audience from different backgrounds
Head and neck anatomy
The document discusses the anatomy of blood vessels, nerves, muscles and other structures in the head and neck region. It provides details on the arterial and venous systems, including the common carotid arteries and internal and external carotid arteries. It also describes the 12 pairs of cranial nerves and 8 cervical spinal nerves that supply the head and neck. An overview is given of the muscles of facial expression, eyes, ears, nose and paranasal sinuses, mouth, pharynx, larynx and neck. The salivary glands, lymph nodes, teeth and other structures are also briefly outlined.
arterial supply of face
The external carotid artery supplies the face and branches into several arteries that vascularize different regions. The lingual artery supplies the tongue, the facial artery is the main artery of the face and gives off branches like the inferior labial and angular arteries. The maxillary artery is a terminal branch that passes through the infratemporal fossa. The occipital and posterior auricular arteries supply structures in the scalp. The ascending pharyngeal artery vascularizes the pharynx.
