This document discusses the lymphatic drainage of the head and neck region. It begins by introducing that lymph from the head and neck drains into deep cervical lymph nodes, which form the jugular trunks that drain into the right lymphatic duct or left thoracic duct. There are approximately 60-70 lymph nodes in the head and neck region, which can be grouped as superficial or deep nodes. Superficial nodes lie above the deep cervical fascia, while deep nodes include the deep cervical nodes, Waldeyer's ring, and midline nodes. The deep cervical nodes surround the internal jugular vein and extend from the skull base to the neck root. Lymph ultimately drains from these deep cervical nodes into the jug

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

- 2. INTRODUCTION • All the lymph from the region of head and neck drains into deep cervical lymph nodes. • The efferents from these nodes form the jugular trunk. • On the right side, jugular trunk drains into right lymphatic duct. • On the left side, jugular trunk drains into thoracic duct.
- 4. INTRODUCTION CONTD… • Out of total 400-450 lymph nodes of human body, ~60-70 nodes are located in the region of head and neck. • Lymph nodes in the head and neck region can be grouped into: • Superficial nodes. • Deep nodes.
- 5. SUPERFICIAL LYMPH NODES • Lie above the investing layer of deep cervical fascia. • Consists of a few small nodes lying superficial to the external jugular and anterior jugular veins. • Includes:- I. Submental nodes. II. Submandibular nodes. III. Buccal nodes. IV. Parotid (preauricular) nodes. V. Mastoid (postauricular or retroauricular) nodes. VI. Occipital nodes. VII. Superficial cervical nodes. VIII. Anterior cervical nodes.
- 6. SUPERFICIAL CERVICAL NODES • These are offshoot of superficial parotid nodes. • Located superficial to upper part of sternocleidomastoid by the side of external jugular vein. AFFERENTS- from 1. Floor of external acoustic meatus. 2. Lobule of the ear. 3. Angle of jaw. 4. Lower part of parotid region. EFFERENTS- drain into • Lower deep cervical nodes.
- 7. ANTERIOR CERVICAL NODES • Arranged along the anterior jugular vein. AFFERENTS- from • Anterior triangle of neck below the hyoid bone. EFFERENTS- drain into • Lower deep cervical nodes.
- 8. DEEP LYMPH NODES • Deep cervical nodes. • Waldeyer’s ring. • Nodes of midline.
- 9. NODES OF MIDLINE • Termed in correspondence to the anatomical area where they exist: • Infrahyoid. • Prelaryngeal. • Pretracheal. • Paratracheal.
- 10. DEEP CERVICAL LYMPH NODES • All the lymph from the region of head and neck drains directly or indirectly into a vertical chain of deep cervical lymph nodes. • Deep cervical lymph nodes surround the internal jugular vein and extend from base of the skull to the root of neck.
- 11. DEEP CERVICAL LYMPH NODES CONTD… o Subdivided into 2 groups by the intermediate tendon of omohyoid. • Upper deep cervical nodes. • Lower deep cervical nodes. UPPER DEEP CERVICAL NODES- • Lie along the upper part of internal jugular vein deep to sternocleidomastoid muscle. LOWER DEEP CERVICAL NODES- • Lie along the lower part of internal jugular vein deep to sternocleidomastoid muscle.
- 12. UPPER DEEP CERVICAL LYMPH NODES JUGULO-DIGASTRIC NODES- • Member of upper deep cervical group. • Located below the posterior belly of digastric muscle. AFFERENTS- from 1. Palatine tonsils. 2. Posterior 1/3rd of tongue. EFFERENTS- into • Lower deep cervical nodes. These nodes act as principal nodes of palatine tonsils.
- 13. LOWER DEEP CERVICAL LYMPH NODES JUGULO-OMOHYOID NODES- • Member of lower deep cervical group. • Lie on the internal jugular vein just above the intermediate tendon of omohyoid. AFFERENTS- from 1. Tongue. 2. Submental nodes. 3. Submandibular nodes 4. Upper deep cervical nodes. EFFERENTS- into • Lower deep cervical nodes. These nodes act as principal nodes of tongue.
