The document discusses the anatomy of the neck region, specifically focusing on cervical fascia and a transverse section of the neck. It defines cervical fascia as sheets of fibrous tissue that invest muscles and organs. It describes the layers of deep cervical fascia - the investing layer, pretracheal fascia, prevertebral fascia, and carotid sheaths. It illustrates these structures on diagrams of fascia of the neck and a transverse section. The summary highlights the organization of deep cervical fascia into distinct layers that surround specific regions like the vertebral column, viscera, and neurovascular bundles.
introduction of neck and boundaries of neck , superficial fascia and structures present with in it, deep cervical fascia types and most importantly spaces with in it mainly about Retro-pharyngeal spaces and applied anatomy along with incision markings.
deals with the anatomy of LS spine coccyx and sacrum. The sacrum and coccyx are two anatomical structures located near the bottom of your vertebral spinal column, below the fifth lumbar vertebra (L5).Below the sacrum is the coccyx, commonly known as the tailbone. The sacrum and coccyx are weight-bearing spinal structures.

These simplified slides by Dr. Sidra Arshad present an overview of the non-respiratory functions of the respiratory tract.
Learning objectives:
1. Enlist the non-respiratory functions of the respiratory tract
2. Briefly explain how these functions are carried out
3. Discuss the significance of dead space
4. Differentiate between minute ventilation and alveolar ventilation
5. Describe the cough and sneeze reflexes
Study Resources:
1. Chapter 39, Guyton and Hall Textbook of Medical Physiology, 14th edition
2. Chapter 34, Ganong’s Review of Medical Physiology, 26th edition
3. Chapter 17, Human Physiology by Lauralee Sherwood, 9th edition

6. CERVICAL FASCIA
&
TRANSVERSE SECTION OF NECK
Definitions:
Cervical = neck region
Fascia = a sheet or band of fibrous tissue that forms an investment for muscles & various
organs of the body
7. SUPERFICIAL CERVICAL FASCIA
• Thin
• Covers the platysma
• May contain considerable amounts of adipose tissue
• Layer of loose connective tissue between dermis & deep fascia
9. DEEP CERVICAL FASCIA… INVESTING LAYER
• Surrounds the neck like a collar
• Splits around trapezius & SCM
• Posteriorly : meets the ligamentum
nuchae
• Attached to hyoid bone anteriorly
• Superiorly – superior nuchal line;
mastoid process, EOP, base of mandible
• Inferiorly – spine of scapula; acromion
process, clavicle & manubrium
• Between angle of mandible & mastoid
process - splits to enclose parotid
gland
• Between angle of mandible & styloid
process – becomes thickened and forms
stylomandibular ligament
• Enclose submandibular gland
10. DEEP CERVICAL FASCIA… PRETRACHEAL FASCIA
• Lies deep to infrahyoid strap muscles
• Attached to midline of hyoid bone &
oblique line of thyroid cartilage laterally
• Splits to enclose & suspend thyroid gland
• Pierced by thyroid vessels
• Laterally – fuses with carotid sheath
• Inferiorly – passes behind brachiocephalic
veins to blend with fibrous pericardium
• Provides a slippery surface for the up &
down gliding of trachea during swallowing &
neck movements
11. DEEP CERVICAL FASCIA… PREVERTEBRAL FASCIA
• Lies in front of prevertebral muscles
• Extends from base of skull in front of longus capitus & rectus capitus lateralis to body of
T3 veterbrae
• Covers muscles in the floor of the posterior triangle of neck
• Cervical plexus & subclavian artery lies deep to it
• Accessory nerve lie superficial to it
• Over the subclavian artery it becomes the axillary sheath
• Does not invest subclavian & axillary veins
• Provides a fixed surface on which pharynx, oesophagus & carotid sheath can
glide during neck movements & swallowing
12. DEEP CERVICAL FASCIA… CAROTID SHEATH
• Surrounds the carotid arteries;
internal jugular vein & vagus nerve
• Thin over the IJV because the vein
needs to be free to dilate during
increased blood flow
• Ansa cervicalis is embedded in anterior
wall
• Cervical symphatetics lie behind it
• Attached to base of skull at margins
of carotid canal
18. Deep cervical fascia
It is organized into several distinct layers
• Investing layer, which surrounds all structures in
the neck;
• Prevertebral layer, which surrounds the vertebral
column and the deep muscles associated with the
back;
• Pretracheal layer, which encloses the viscera of
the neck;
• Carotid sheaths, which receive a contribution
from the other three fascial layers and surround
the two major neurovascular bundles on either
side of the neck.
24. SUBMANDIBULAR GANGLION
• Parasympathetic peripheral
ganglion
• Relay station for secretomotor
fibres to submandibular and
sublingual salivary glands
• Topographically related to
lingual nerve
• Functionally connected to
facial nerve (chorda tympani)
• Lies on hyoglossus muscle just
above deep part of
submandibular gland
• Suspended by lingual nerve by
two roots
