Back of head region anatomy
Back of head region anatomy- Head and neck anatomy is important when considering pathology affecting the same area In radiology, the 'head and neck' refers to all the anatomical structures in this region excluding the central nervous system, that is, the brain and spinal cord and their associated vascular structures and encasing membranes ie the meningesThe Organs of the Head include the ear, the eye, the nose and sinuses, the salivary glands, and the oral cavity The ear can be divided in to three sections the external ear, the middle ear, and the inner ear The external ear functions to capture and direct sound waves through the external acoustic meatus to reach the tympanic membrane (ear drum)
In other words, there is a muscle on the forehead (frontalis) and one on the back of the head (occipitalis), but there is no muscle across the top of the head Instead, the two bellies are connected by a broad tendon called the epicranial aponeurosis , or galea aponeurosis (galea = The neck refers to the collection of structures that connect the head to the torso It is a complex structure composed of many bones, muscles, nerves, blood vessels, lymphatics, and other connective tissues The cervical spine is the bony part of the neck Its primary function is to provide support for the skull, while still allowing for movement It is the most flexible part of the Head and upper neck disorders may be called craniovertebral (or craniocervical) junction abnormalities (CVJ) The CVJ is one of the unique and complex areas of your body, as this is where your brain transitions to your spine The CVJ is composed of the occipital bone, atlas (C1), and axis (C2), along with a network of complex nerve and vascular
The neck is the start of the spinal column and spinal cord The spinal column contains about two dozen interconnected, oddly shaped, bony segments, called vertebrae The neck contains seven ofThe occipital bone (/ ˌ ɒ k ˈ s ɪ p ɪ t əl /) is a cranial dermal bone and the main bone of the occiput (back and lower part of the skull)It is trapezoidal in shape and curved on itself like a shallow dish The occipital bone overlies the occipital lobes of the cerebrumAt the base of skull in the occipital bone, there is a large oval opening called the foramen magnum, which allows the The majority of blood draining from the head is passed into three pairs of veins • vertebral veins Within the brain all veins lead to the internal jugular veins The external jugular veins are smaller than the internal jugular veins and lie superficial to them They receive blood from superficial regions of the face, scalp and neck
This is a region of the neurocranial portion of the head and includes the temporal and infratemporal fossae, superior and inferior to the zygomatic arch, respectively Oral region This is a median region of the face or viscerocranial portion of the head and includes the oral cavity , teeth , gingivae , tongue, palate, and the region of the palatine tonsils Neck layers • Prevertebral Layer • Surrounds the vertebral column and its associated muscles (scalence, prevertebral, and deep muscles of the back) • In the inferior region of the neck, the fascia surrounds the brachial plexus and subclavian artery, and here it The occipital bone is the trapezoidshaped bone at the lowerback of the cranium (skull) The occipital bone houses the back part of the brain and is one of seven bones that come together to form the skull It is located next to five of the cranium bones
Posterior (or dorsal) means the opposite of anterior "back of" or "behind/on the back" This is easy to remember because "posterior" is another word for your rear end, which is on your backside An anatomy test question might ask, "Your sternum is _____ to your spine" The answer is that your sternum is anterior to the spineIn other words, there is a muscle on the forehead ( frontalis) and one on the back of the head ( occipitalis ), but there is no muscle across the top of the head Instead, the two bellies are connected by a broad tendon called the epicranial aponeurosis, or galea aponeurosis (galea =The Crown begins at the point where the top of the head begins to curve downward to the back of the head and ends at the point just above the Occipital bone It is a semicircular area Occipital BoneThe Occipital Bone is the small bony protrusion at

Extrinsic and intrinsic The back functions are many, such as to house and protect the spinal cord , hold the body and head upright, and adjust the movements of the upper and lower limbsAncient Greek and Latin words are used to build anatomical terms A standard reference position for mapping the body's structures is the normal anatomical position Regions of the body are identified using terms such as "occipital" that are more precise than common words and phrases such as "the back of the head" In addition to housing main parts of the nervous system — the brain and spine — and the start of the digestive system, the head contains many important sensory organs
The anatomical regions (shown) compartmentalize the human body Just like on a map, a region refers to a certain area The body is divided into two major portions axial and appendicular The axial body runs right down the center (axis) and consists of everything except the limbs, meaning the head, neck, thorax (chest and back), The head and neck receives the majority of its blood supply through the carotid and vertebral arteries This article shall explore the anatomy of this arterial system – its anatomical course, branches, and clinical correlationsC2 and C3 Posterior head and neck • T4 Nipple • T10 – Umbilicus Natural Variants The dermatome is a basic concept, yet much variability exists between dermatome maps in standard anatomy and medical guideline textbooks A review of 14 different dermatome maps by Lee et al showed striking variations within each individual map 7
The muscles of the back categorize into three groups The intrinsic or deep muscles are those muscles that fuse with the vertebral column The second group is the superficial muscles, which help with shoulder and neck movements The final group is the intermediate muscles, which help with the movement of the thoracic cage Only the intrinsic muscles are considered true backThe muscle has a frontal belly and an occipital (near the occipital bone on the posterior part of the skull) belly In other words, there is a muscle on the forehead ( frontalis) and one on the back of the head ( occipitalis ), but there is no muscle across the top of the headThe back has different muscle groups that work together to allow movement There are groups of muscles that move the Head Shoulders Upper arms Spine (vertebral column) Upper leg (thigh) Other muscles beyond the back also help move the head, shoulders, arms, and legs For example, some muscles located in the chest also help move the shoulders
Infraorbital Region The infraorbital region of head is situated below the orbital region and corresponds to the upper part of the anterior surface of the maxilla The infraorbital foramen lies in this region about 1 cm below the infraorbital margin consistent together with the supraorbital notch or foramen The knowledge of its location is essential for providing infraorbital In the neck and head exterior to the skull, the external carotid artery provides blood flow to the skin, muscles, and organs Several major arteries including the facial, superficial temporal, and occipital arteries branch off from the external carotid to provide blood to the many superficial structures of the headFemale Head Muscles Anatomy Back Clip Art by Decade3D 5 / 142 the head muscles Clipart by Eraxion 5 / 50 Female Head Muscles Anatomy Back Stock Illustration by Decade3D 4 / 500 Male backbone with skull posterior view Stock Illustrations by woodoo 3 / 244 Thoracic spine anatomy posterior view Clip Art by woodoo 3 / 176 Blood supply of the brain, eps10 Stock Illustrations by
