Human Anatomy Quiz - 10th Class

The anterior and lateral facets of the calcaneus form the articulation with the talus bone.

The rotator cuff muscles are a group of four muscles that surround the shoulder joint. They help to stabilize the shoulder joint and perform various movements.

The lambdoid suture is a joint in the skull that connects the parietal bones and the occipital bone.

The sagittal plane divides the body vertically into right and left halves.

The total lung capacity in a healthy adult male is approximately 6 liters. This includes all the air that can be held in the lungs after a maximum inhalation.

The three fat pads associated with the elbow joint are the supinator fat pad and the posterior fat pad.

The right coronary artery supplies blood to the right side of the heart. The circumflex artery is a branch of the left coronary artery.

The aortic arch is a curved part of the aorta that lies behind the esophagus. It can cause compression of the esophagus, leading to difficulty swallowing.

The semilunar valves are open and the atrioventricular valves are closed during ejection, allowing blood to be pumped out of the ventricles.

The sequence of structures that air travels through as it enters the lungs, starting after the bronchi, is: respiratory bronchiole, terminal bronchiole, alveolar duct, alveolus.

The meninges are a protective covering of three layers: the dura mater, arachnoid mater, and pia mater.

Proprioceptors detect changes in muscle tension, joint position, and body movement.

Spongy bone, a type of bone tissue with a porous structure, is present in the epiphyses of a long bone.

Volkmann's canals, also called perforating canals, connect the haversian canals to the outer surface of the bone, providing a pathway for blood vessels and nerves.

Albumin, a large protein, is too big to pass through the filtration membrane of the glomerular capsule.

The visceral pleura is the thin membrane that directly covers the lungs.

The point on the skull where the sagittal and lambdoid sutures meet.

A large, triangular opening in the posterior aspect of the vertebral arch, which allows passage of the spinal cord.

No intervertebral disc is present between the first and second cervical vertebrae (C1 and C2).

The spinal cord is enlarged in this region to accommodate the nerves that innervate the lower limbs.

An excessive outward curvature of the thoracic spine, resulting in a rounded back. It can be caused by developmental anomalies or osteoporosis.

An excessive inward curvature of the lumbar spine, resulting in a swayback appearance. It is often caused by an anterior rotation of the pelvis.

The vertebral column provides support for the weight of the body, protects the spinal cord and nerves, and contributes to posture and movement.

The spinal cord is responsible for transmitting sensory information to the brain and motor commands from the brain to the body.

A condition where the spine curves sideways, often caused by differences in muscle strength, length of limbs, or issues with intervertebral discs.

The bony prominence on the upper end of the humerus, not part of the condyle.

A small, triangular carpal bone that sits on the palmar surface of the trapezium and articulates only with the trapezium. It's not attached to any other carpal bones.

The process on the ulna that extends distally.

The carpometacarpal joint of the thumb, which has a unique saddle-shaped articulation allowing for opposition movement.

A common injury to the acromioclavicular joint, involving the separation of the clavicle from the scapula.

A long bone in the shoulder that connects the sternum to the scapula.

This type of joint allows for gliding movements, found in the carpometacarpal and intermetacarpal joints, except for the thumb's carpometacarpal joint.

The point where the main pancreatic duct and the bile duct join together.

The renal pelvis is situated most posteriorly, while the renal vein lies anterior to the renal artery.

The diaphragm is the main muscle responsible for inhalation, creating negative pressure in the chest cavity.

The abdominal aorta divides into the common iliac arteries at the level of the crest of the ilium.

The stomach and duodenum are the primary sites for the breakdown of food through mechanical churning and enzymatic digestion.

Most water reabsorption takes place in the ascending colon, contributing to the formation of solid feces.

The inferior ramus of the pubis is part of the pelvic floor and doesn't directly form the inlet.

Fertilization usually occurs in the ampulla, the wider portion of the uterine tube, where the egg is typically present after ovulation.

Axillary nerve damage leads to inability to flex the elbow and to abduct the arm, as well as loss of sensation in the lateral arm.

Syndactyly refers to the fusion or webbing of fingers or toes.

The rib tubercle, a small bump on the rib, articulates with the transverse process of the corresponding vertebra to form the costovertebral joint.

The pleural cavity is the space between the visceral and parietal pleura, containing a thin layer of serous fluid.

The sternal angle, also called the angle of Louis, lies at the level of the intervertebral disc between T4 and T5 vertebrae. It marks the point where the second rib articulates with the sternum.

Trabeculae carneae are irregular muscle ridges found in the ventricles of the heart, but not in the atria.

The interventricular septum, the wall dividing the ventricles, contains the conus arteriosus, which is the smooth outflow tract of the right ventricle leading to the pulmonary trunk.

Alveoli, small air sacs in the lungs, are the primary sites of gas exchange between the air and the blood.
