Practical: Dog Flashcards
Inguinal ring
- Located medially to the pectineus muscle
- Male:
- Within the skin fold suspending the prepuce
- Female:
- Deep to the mammary gland
Bladder
- Only palpable when full
- Caudoventral abdominal wall is grabbed
- Movement of urine can be felt
Canalis femoralis
Composed of:
- Sartorius
- Gracillis
- Vastus medialis
Structures located inside the femoral canal
- Femoral A./v.
- Proximal caudal femoral artery
- Saphenous nerve
What is cardiac border auscultation used for?
In order to locate the puncta maxima of the heart
List the cardiac borders
- Pulmonary trunk
- Aorta
- Left AV
- Right AV
Cardiac border: Pulmonary trunk
Left side:
- 3rd intercostal space
- Above the sternum
Cardiac border: Aorta
Left side:
- 4th intercostal space
- In line with shoulder
Cardiac border: Left AV
Left side:
- 5th intercostal space
- Distal 3rd
Cardiac border: Right AV
Right side:
- 4th intercostal space
- Genu costae
Cardiac dullness
- Percussion between the ribs
- Determines the borders of the heart
- Thickening of the lungs around the heart gives relative dullness
Cardiac dullness: Left side
- 4th-6th intercostal space
- Distal third
Cardiac dullness: Right side
- 4th-5th intercostal space
- Distal third
The loudest sound observed during percussion is referred to as…
Punctum maximum
List the nerve blocks of the hindlimb
- Tibial nerve block
- Fibular nerve block
Fibular nerve block
- Nerve passes over the head of the fibula
- Can be palpated with the fingernail
- Aspirate + Inject parallel to the skin
Tibial nerve block
- Nerve can be felt in the skin adjacent to the CCT
- Aspirate + Inject parallel to the skin
Radial nerve block
- Supplies extensors of the elbow, carpus + digits
- Enters the triceps distal to the teres major muscle
- Passes in front of the lateral epicondyle of humerus
- Inject in a ventral position
Ulnar nerve
- Supplies the flexors of the antebrachium
- Originates with the median nerve
- Travels on the medial aspect of the humerus
- Branches passes through the carpal canal
Ulnar nerve: Injection site
Between the tendons of:
- m. ulnaris lateralis
- m. flexor carpi ulnaris
At the level of the accessory carpal bone, accessed laterally
Mental nerve block
- Emerges from the mental foramen
- Acts on the lower lip and lower teeth
Inferior alveolar nerve block (‘Alveolaris mandibularis’)
- Enters mandibular foramen
- Supplying teeth and gums
- Needle is inserted medial to the mandibular notch
Lingual nerve block
- Originates from the mandibular nerve
- Travels rostrally to the tongue
- Between styloglossus + mylohyoid muscles
Median nerve block
Located between:
- Radial carpal flexor
- Superficial digital flexor
Accessed on medial side
