Lecture 25 Flashcards
(27 cards)
What are the veins called where sedatives are injected?
Superficial Veins
Where is the best site for intramuscular injection in the upper arm?
Deltoid muscle
Where is the location of the Deltoid muscle?
Laterally covering the shoulder joint
What is the action of the Biceps Brachii muscle?
Powerful flexor and supinator of forearm
What is the function of the Brachialis muscle?
Flexion of the forearm
What is the function of the Triceps Brachii muscle?
Extension of forearm
Where is the best site for intramuscular injection in the lower limb?
Gluteus Medius muscle
Where is the location of the Gluteus Medius muscle?
Superiorly in the buttock
Where is the attachment of the Gluteus medius and minimus and what is the action of these muscle?
Lateral side of the hip and their contraction will cause abduction
What is the large nerve found in the lower limb region?
Sciatic nerve
What does the Sciatic nerve supply?
- All of the muscles below the knee
- Posterior muscles above the knee
- Sensory to these regions
What are the 2 parts of the Sciatic nerve?
1) Tibial nerve
2) Common fibular nerve (goes laterally)
Where does the Sciatic nerve run through?
Lower and inner quadrant of the gluteal region
Where is the safe area for the injection?
Into the upper and outer quadrant
What are the Quadricep muscles innervated by?
The femoral nerve
List the boundaries of the Cubital Fossa
- Medially: Pronator teres muscle
- Laterally: Brachioradialis muscle
- Superiorly: line joining humeral Epicondyles
- Floor: Brachialis muscle
What is the Roof of the Cubital Fossa?
Deep fascia of the forearm and medial side of biceps aponeurosis
What veins make up the Cubital Fossa?
- On the medial side is the Basilic vein
- On the lateral side is the Cephalic vein
Which vein is used to inject
intravenous drugs or take blood samples?
Median cubital vein
If the needle is injected too deeply, where can it go?
- Median nerve - supplies forearm and hand muscles
- Brachial artery
- Biceps tendon
Where does the Basilic & Cephalic veins drain into?
Axillary vein
Where does the Axillary drain into, and where does this drain into?
Subclavian vein
- This vein drains into the Brachiocephalic vein
Which arteries make up the Palmer arches?
- Radial artery
- Ulnar artery
What does the Axillary nerve supply?
Deltoid and skin
