Which of the following nerve innervates the flexor carpi ulnaris muscles?
- A.
Radial
- B.
Ulnar
- C.
Median
- D.
Musculocutaneous
Correct Answer
B. UlnarExplanation
The flexor carpi ulnaris muscle is innervated by the ulnar nerve, which is one of the major nerves of the upper limb. Innervation refers to the supply of nerve fibers to a muscle, allowing it to contract and perform its function.Rate this question:

Which muscle of the shoulder region is not innervated by the branch of brachial plexus?
- A.
Trapezius
- B.
Supraspinatus
- C.
Infraspinatus
- D.
Long head of triceps
Correct Answer
A. TrapeziusExplanation
The trapezius muscle is not innervated by a branch of the brachial plexus. It is innervated by the accessory nerve (CN XI), which is not a branch of the brachial plexus. The supraspinatus, infraspinatus, and long head of triceps muscles are all innervated by branches of the brachial plexus.Rate this question:

Which of the following spinal nerve does not contribute to the formation of brachial plexus?
- A.
1st cervical
- B.
Last cervical
- C.
1st Thoracic
- D.
6th Cervical
Correct Answer
A. 1st cervicalExplanation
The 1st cervical spinal nerve, also known as the C1 nerve, does not contribute to the formation of the brachial plexus. The brachial plexus is formed by the lower four cervical nerves (C5-C8) and the first thoracic nerve (T1). The brachial plexus is responsible for innervating the upper limb, so the absence of the 1st cervical nerve in its formation does not affect the function of the brachial plexus.Rate this question:

Which nerve form the secondary loop for the passage of the brachial/axillary artery?
- A.
Pectoral
- B.
Radial
- C.
External thoracic
- D.
Median and musculocutaneous
Correct Answer
A. PectoralExplanation
In the brachial plexus, the nerves form several loops known as arterial loops or neurovascular loops. These loops help protect the major arteries of the upper limb, including the brachial artery. The nerve that forms the secondary loop for the passage of the brachial or axillary artery is the Pectoral nerve.Rate this question:

Which of the following is the largest nerve of the body?
- A.
Sciatic
- B.
Radial
- C.
Median
- D.
Saphenous
Correct Answer
A. SciaticExplanation
The sciatic nerve is the largest nerve in the body. It is a major nerve that originates in the lower back and extends down the back of the thigh and leg. It supplies motor and sensory innervation to the muscles of the lower leg and foot. The sciatic nerve is responsible for transmitting signals between the spinal cord and the lower extremities, allowing for movement and sensation. It is larger in diameter compared to the radial, median, and saphenous nerves, making it the correct answer to the question.Rate this question:

The three nerves of brachial plexus that reaches upto digit are
- A.
Radial, Ulnar and Median
- B.
Radial, Ulnar and Axillary
- C.
Median, Ulnar and Thoraco dorsal
- D.
Radial, Pectoral and Median
Correct Answer
A. Radial, Ulnar and MedianExplanation
The correct answer is Radial, Ulnar and Median. The brachial plexus is a network of nerves that originate from the spinal cord in the neck and innervate the upper limb. The radial nerve supplies the muscles that extend the wrist, fingers, and thumb, as well as the skin on the back of the hand. The ulnar nerve supplies the muscles that flex the wrist and fingers, as well as the skin on the medial side of the hand. The median nerve supplies the muscles that flex the wrist and fingers, as well as the skin on the palmar side of the hand.Rate this question:

The long head of triceps is innervated by
- A.
Radial
- B.
Ulnar
- C.
Median
- D.
Axillary
Correct Answer
A. RadialExplanation
The long head of triceps is innervated by the radial nerve. The radial nerve is responsible for supplying motor innervation to the triceps muscle, which allows for extension of the elbow joint. The other options, ulnar, median, and axillary nerves, do not innervate the long head of triceps.Rate this question:

Which of the following nerves are found in the femoral canal?
- A.
Femoral nerve
- B.
Saphenous nerve
- C.
Peroneal nerve
- D.
Tibial nerve
Correct Answer
B. SapHenous nerveExplanation
The saphenous nerve is found in the femoral canal. The femoral canal is a passageway in the upper thigh where the femoral nerve, femoral artery, and femoral vein pass through. The saphenous nerve is a branch of the femoral nerve that travels down the leg and provides sensory innervation to the skin on the medial side of the leg and foot. Therefore, it is correct to say that the saphenous nerve is found in the femoral canal.Rate this question:

The blind spot in the eye of the horse, known as the "tapetum lucidum," contributes to which of the following?
- A.
Night vision
- B.
Color vision
- C.
Depth perception
- D.
Peripheral vision
Correct Answer
A. Night visionExplanation
The tapetum lucidum is a reflective layer located behind the retina in the eyes of many animals, including horses. It helps to enhance night vision by reflecting light that passes through the retina back onto the photoreceptor cells, particularly in low-light conditions. This reflection increases the sensitivity of the retina to light and improves the animal's ability to see in dim light. As a result, horses have better night vision than humans, which is advantageous for their survival in their natural habitats.Rate this question:

Ruminant stomach get blood supply by
- A.
Coeliac artery
- B.
Anterior mesenteric artery
- C.
Posterior mesenteric artery
- D.
Iliac artery
Correct Answer
A. Coeliac arteryExplanation
The correct answer is Coeliac artery. The coeliac artery is responsible for supplying blood to the stomach in ruminant animals. It is a major branch of the abdominal aorta and provides oxygenated blood to the stomach, liver, and spleen. The coeliac artery ensures that the stomach receives the necessary nutrients and oxygen for digestion and other metabolic processes.Rate this question:

The sciatic nerve emerge out of pelvic cavity through
- A.
Obturator foramen
- B.
Greater sciatic foramen
- C.
Foramen ovale
- D.
Inguinal canal
Correct Answer
B. Greater sciatic foramenExplanation
The sciatic nerve emerges out of the pelvic cavity through the greater sciatic foramen. This is a large opening located in the pelvis, through which the nerve passes to exit the pelvic region and extend down the leg. The greater sciatic foramen provides a pathway for the sciatic nerve to transmit signals between the lower limb and the central nervous system.Rate this question:

Which of the following abdominal muscle does not contribute to the formation of linea alba?
- A.
Obliquous abdominis externus
- B.
Obliquous abdominis internus
- C.
Rectus abdominis
- D.
Transverse abdominis
Correct Answer
C. Rectus abdominisExplanation
The rectus abdominis muscle does not contribute to the formation of linea alba. Linea alba is a fibrous band that runs vertically down the midline of the abdomen and is formed by the aponeurosis (a flat tendon) of the obliquus abdominis muscles and the transverse abdominis muscle. The rectus abdominis muscles are located on either side of the linea alba and do not directly contribute to its formation.Rate this question:
