Do you have fascia in your neck?
The structures found in the neck are surrounded by a layer of subcutaneous tissue called the superficial fascia, while there are also layers of deep cervical fascia which distribute the structures in the neck into different compartments.
Which two muscles does the investing fascia of the neck enclose?
The superficial layer is also known as the investing layer of deep cervical fascia. It envelops the trapezius, sternocleidomastoid, and muscles of facial expression. It also contains the submandibular and parotid salivary gland as well as the muscles of mastication (the masseter, pterygoid, and temporalis muscles).
What is the function of investing fascia?
The prevertebral fascia is continuous with the transversalis fascia of the thorax and abdomen. The prevertebral fascia functions to help in allowing the esophagus, pharynx, and carotid sheaths to glide unobstructed by the longus coli and scalene muscles during neck flexion, extension, and rotation.
Does neck have superficial fascia?
The superficial cervical fascia is the subcutaneous layer of the skin in the neck. This thin layer contains the muscles of facial expression, including the platysma muscle in the neck. The cutaneous nerves, superficial vessels, and superficial lymph nodes course within the superior cervical fascia.
Is there fascia in the head?
Head fascia covers the skull and merges and entwines into the neck. When we accidentally pull our neck, most of the time the fascia has been ‘jerked’ out its original shape resulting in pain. Fascia in the head becomes very tight when we are fatigued, dehydrated or stressed, leading to headaches.
What is the investing layer of cervical fascia?
Describe the attachment and structures enclosed by investing layer of Deep Cervical Fascia. It encircles the neck like a collar deep to superficial fascia.
Where does the investing fascia attach to the skull?
The investing fascia can be thought of as a tube; with superior, inferior, anterior and posterior attachments: Superior – attaches to the external occipital protuberance and the superior nuchal line of the skull. Anteriorly – attaches to the hyoid bone.
How does the neck fascia prevent the spread of infection?
This is of clinical importance as a pathway for the spread of infection. The neck fascia compartmentalises structures within the neck. These layers of tough fascia can limit the spread of infection (for example, a superficial skin abscess may be prevented from spreading deeper into the neck by the investing fascia).
Where does the pretracheal fascia surround the neck?
Fig 3 – Transverse section of the neck, showing the pretracheal fascia in red. The prevertebral fascia surrounds the vertebral co lumn and its associated muscles; scalene muscles, prevertebral muscles, and the deep muscles of the back.
