Clinical Examination lymph nodes
Dr. Karima Al Salihi
Examination of superficial lymphnodes of
animals:
Objectives: to compared each paired node for
size and consistency with the contralateral
node.
Method: Grossly enlarged lymph nodes may
have been seen during observation of the
patient before it is handled. Observation
andpalpation is possible when the animal is
restrained.
Anatomical Location of lymphnodes (LN): Lymph
nodes are round or bean-shaped structures that are
widely distributed throughout the body. Imbedded in
connective tissue or fat, they are concentrated in the
cervical, axillary, and inguinal regions – the neck,
armpits, and groin, respectively. They are typically
less than 1⁄2 inch in length, depending on the size of
the animal. The lymph nodes filter the lymph before
returning it to the veins [2,9].
Submandibular lymph nodes: situated and are
palpable on the medial aspect of the ‘angle of the jaw’
where the horizontal and vertical rami of the mandible
meet. (Normal size is 1.5 to 2 cm)
10 clinical examination lymph nodes
Prescapular lymph nodes: It lies subcutaneously and underneath the
cutaneous muscle just anterior to the shoulder joint (Normal size 1 cm ×
3.5 cm)
Axillary lymph nodes: Found on each side of the chest in the armpit
area. Normally only palpable in young calves without heavy muscling
(Normal size 1.5 cm)
Popliteal lymph nodes: These nodes are found surrounded by dense
muscle tissue immediately behind the stifle. It found on each rear leg on
the opposite side of the knee. They are relatively superficial and easy to
feel (normal size 1-1.5 cm)
Inguinal lymph nodes: These are usually palpable as a small group of
fairly mobile and firm structures adjacent to the inguinal canal. (Normal
size 0.5 cm)
Supramammary lymph nodes: These are normally readily palpated on
the caudal aspect of the udder just above the upper limit of the mammary
glandular tissue, normal size 2.5 cm [8,23] (Figure 12).
