Collects lymph from scrotum
Inguinal nodes
26
Collects lymph from perineum
Inguinal nodes
27
Collects lymph from buttocks
Inguinal nodes
28
Collects lymph from the abdominal wall
Inguinal nodes
29
Left supraclavicular lymph node is also know as
Virchow's node
30
Enlargement in virchow's node is a sign of
Gastrointestinal GI malignancy
31
The deep lymphatic vessels of the head and neck arise from
The deep cervical lymph nodes
32
Deep cervical lymph nodes converge to form
The left and right jugular lymphatic trunks
33
Forms the the right lymphatic duct at the roof of the necks
Right jugular lymphatic trunk
34
Lect jugular lymphatic trunk combines with
The thoracic duct and the root of the neck
35
Lymph nodes act as
A barrier against disease
36
Lymph nodes are
Small bean shaped structures usually less than 2.5cm, 1 inch in length.
37
Lymph nodes are (feel)
Soft, non-palpable structures.
38
The point at which arteries carrying nutrients to the lymph node and veins leave it
Hilum
39
Afferent lymphatic vessels enter the lymph node through
The capsule peripherally
40
Efferent lymphatic vessels leave the node via
The hilum
41
Afferent takes lymph from
Peripheral sites to the node
42
Efferent takes the processed lymph from
The nodes back to the venous circulation.
43
Important lymph nodes you should know
Cervical lymph nodes Axillary lymph nodes Supraclavicular lymph nodes Inguinal lymph nodes
44
Three superficial regions where lymph nodes tend to form groups
1) Inguinal nodes in the groin 2) Axillary nodes in the armpit 3) Cervical nodes in the neck
45
Inguinal lymph nodes are palpable in
Healthy people
46
Cervical nodes, especially submandibular nodes are palpable because
Chronic trauma and infection are common in these regions.
47
Lymph nodes of the head and neck can be divided into two groups
1) Superficial lymph nodes (ring) 2) Deep lymph nodes (vertical)
48
How many preauricular lymph nodes are there?
1-3
49
Posterior auricular nodes (mastoid) are situated on
The lateral mastoid process behind auricle (behind ear).
50
The parotid nodes are located
Superficially to the parotid gland
51
Occipital nodes are situated at
The apex of the posterior triangle of the neck.
52
Number of submental nodes
3 - 4
53
Location of submental nodes
Lies below the chin
54
Submental nodes drain into
Submandibular nodes or directly into the deep cervical nodes.
55
Submandibular nodes lie on
The surface of the submandibular salivary gland or embedded within it.
56
57
Superficial cervical nodes lie
Along the course of the external jugular vein.
58
Location of deep cervical nodes
They are scattered in the carotid sheath in front and behind the internal jugular vein.
59
Deep cervical nodes lie undercover of the
Sternocleidomastoid muscle
60
Deep cervical nodes are divided into
Upper and lower groups
61
Jugulo digastric nodes lie
Just below the posterior belly of the digastric muscle.
62
Jugulo digastric nodes are clinically palpable
Below angle of the mandible
63
Most important group of lower deep cervical group
Jugulo omohyoid
64
Important examples of deep cervical nodes
Retropharyngeal nodes Jugulodigastric (tonsilar) nodes Jugulo omohyoid nodes Supraclavicular nodes
65
Retropharyngeal nodes lie in
The retropharyngeal space, between the pharyngeal wall and the prevertebral fascia.
66
The inguinal nodes are found in
The upper aspect of the femoral triangle.
67
Number of inguinal nodes
1 - 20
68
Inguinal nodes are divided into 2 groups
Superficial and deep
69
Superficial inguinal nodes shape
Inverted L shape
70
Horizontal group of inguinal nodes, group along
The lower border of the inguinal ligament.
71
Vertical group of inguinal nodes
Along the great saphenous vein.
72
Deep inguinal nodes
Found in one to three in numbers and are most commonly found on the medial aspect of the femoral vein.
73
The afferent supply of deep inguinal nodes is from
The deep lymphatic trunks of the thigh which accompany the femoral vessels.
