What is the soft spot (incomplete bone formation) between the skull bones of an infant?
-
Fontanelle
-
Tubercle
-
Vertebra
Correct Answer
A. FontanelleExplanation
The soft spot between the skull bones of an infant is called a fontanelle. This is an area where the bones have not fully formed and are still flexible, allowing for the growth and development of the baby's brain. The fontanelle is important as it allows for the compression of the skull during childbirth and also provides room for the brain to grow rapidly in the first year of life.Rate this question:

What is the shaft, or mid-portion, of a long bone?
-
Ribs
-
Diaphysis
-
Xiphoid Process
Correct Answer
A. DiaphysisExplanation
The correct answer is Diaphysis. The diaphysis refers to the shaft or mid-portion of a long bone. It is the long, cylindrical part of the bone between the two ends, known as the epiphysis. The diaphysis is responsible for providing support and strength to the bone, as it contains compact bone tissue. It also houses the medullary cavity, which contains bone marrow. The diaphysis plays a crucial role in the overall structure and function of long bones.Rate this question:

Bone
Correct Answer
A. Compact BoneExplanation
Compact bone is a type of hard, dense bone tissue that is typically found in the outer portion of bones. It provides strength and support to the skeletal system and helps protect the internal structures of the bone. Compact bone is made up of tightly packed layers of mineralized matrix, which gives it its dense and solid nature. This type of bone tissue is responsible for withstanding the mechanical stresses and strains that the skeleton experiences during daily activities.Rate this question:

-
Red Bone Marrow
Correct Answer
A. Red Bone MarrowExplanation
Red bone marrow is found in cancellous bones and is the site of hematopoiesis, which is the process of blood cell formation. Red bone marrow contains stem cells that differentiate into various types of blood cells, including red blood cells, white blood cells, and platelets. These blood cells are essential for carrying oxygen, fighting infections, and clotting.Rate this question:

What is narrow, slit-like opening in or between bones?
-
Fissure
-
Tuberosity
-
Malleolus
Correct Answer
A. FissureExplanation
A fissure is a narrow, slit-like opening in or between bones. It is a term used in anatomy to describe a long, deep cleft or groove that can be found in various parts of the body, such as the brain, lungs, or bones. It is different from tuberosity, which refers to a rounded prominence or bump on a bone, and malleolus, which is a bony protuberance on either side of the ankle joint. Therefore, the correct answer is fissure.Rate this question:

What is the thin layer of cartilage covering the bone in the joint space?
-
Epiphyseal plate
-
Fossa
-
Articular Cartilage
Correct Answer
A. Articular CartilageExplanation
Articular cartilage is the correct answer because it refers to the thin layer of cartilage that covers the bone in the joint space. This cartilage helps to reduce friction and absorb shock between bones during movement, allowing for smooth and pain-free joint motion. The epiphyseal plate is a growth plate found in growing bones, while a fossa is a shallow depression in a bone.Rate this question:

What is the connection on either side of the head between the temporal bone of the skull and mandibular bone of the jaw?
-
Temporomandibular Joint
-
Olecranon
-
Haversian Canals
Correct Answer
A. Temporomandibular JointExplanation
The temporomandibular joint is the connection on either side of the head between the temporal bone of the skull and the mandibular bone of the jaw. This joint allows for the movement of the jaw, such as opening and closing the mouth, chewing, and speaking. It is a complex joint that involves a combination of hinge and sliding motions, allowing for the smooth and coordinated movement of the jaw. Dysfunction or disorders of the temporomandibular joint can result in pain, difficulty in jaw movement, and other symptoms.Rate this question:

Name is each end of a long bone; the area beyond the epiphyseal plate.
-
Epiphysis
-
Fossa
-
Yellow Bone Marrow
Correct Answer
A. EpiphysisExplanation
Epiphysis refers to the name given to each end of a long bone, specifically the area beyond the epiphyseal plate. The epiphyseal plate is a cartilaginous area in growing bones that allows for longitudinal growth. The epiphysis is responsible for the attachment of tendons and ligaments, as well as the formation of joints with other bones. It is also a site for red bone marrow production, which is responsible for blood cell formation. Therefore, the correct answer is Epiphysis.Rate this question:

Name the round process on both sides of the ankle joint. The lateral malleolus is part of the fibula, and the medial malleolus is part of the tibia.
-
Malleolus
-
Sella Turcica
-
Osteoclast
Correct Answer
A. MalleolusExplanation
The correct answer is Malleolus. The malleolus refers to the bony prominence on both sides of the ankle joint. The lateral malleolus is part of the fibula, which is the smaller bone in the lower leg, while the medial malleolus is part of the tibia, which is the larger bone in the lower leg. These structures help provide stability and support to the ankle joint during movement.Rate this question:

Name one of the mineral constituents of bone.
-
Iron
-
Calcium
-
Facial Bones
Correct Answer
A. CalciumExplanation
Calcium is one of the mineral constituents of bone. It plays a crucial role in maintaining bone strength and density. Calcium is necessary for the formation and development of bones, and it helps in the regulation of bone remodeling processes. It is also involved in muscle contraction, nerve function, and blood clotting. Adequate calcium intake is essential for maintaining healthy bones and preventing conditions like osteoporosis.Rate this question:

Movement away from the midline of the body.
-
Abduction
-
Visceral muscle
-
Pronation
Correct Answer
A. AbductionExplanation
Abduction refers to the movement of a body part away from the midline of the body. This movement is typically observed in the limbs, such as when lifting the arm or spreading the fingers apart. In contrast, pronation refers to the rotation of the forearm so that the palm faces downwards, and visceral muscle refers to the smooth muscle found in the internal organs. Therefore, the correct answer is abduction, as it specifically describes the movement away from the midline.Rate this question:

The muscle connected to internal organs; involuntary or smooth muscle.
-
Flexion
-
Visceral Muscle
-
Skeletal Muscle
Correct Answer
A. Visceral MuscleExplanation
Visceral muscle, also known as smooth muscle, is the correct answer because it is the type of muscle that is connected to internal organs and functions involuntarily. This type of muscle is found in the walls of organs such as the stomach, intestines, and blood vessels, and it helps to control their movements. Unlike skeletal muscle, which is under voluntary control, visceral muscle works automatically and is responsible for functions such as digestion and circulation.Rate this question:

Straightening of a flexed limb.
-
Rotation
-
Extension
-
Supination
Correct Answer
A. ExtensionExplanation
Extension refers to the straightening of a flexed limb. When a joint is extended, it moves from a bent or flexed position to a straight or extended position. This movement increases the angle between the bones of the joint, allowing for greater range of motion. For example, when a person straightens their arm from a bent position, they are performing extension at the elbow joint. Similarly, when the knee is straightened from a bent position, it is also an example of extension.Rate this question:

Bending the sole of the foot downward toward the ground.
-
Plantar Flexion
-
Straited muscle
-
Abduction
Correct Answer
A. Plantar FlexionExplanation
Plantar flexion refers to the movement of bending the sole of the foot downward toward the ground. This movement is commonly associated with activities such as pointing the toes or standing on tiptoes. The term "plantar" refers to the sole of the foot, and "flexion" indicates bending or decreasing the angle between two body parts. This movement is primarily controlled by the contraction of muscles in the calf, such as the gastrocnemius and soleus muscles. Plantar flexion is an important movement for activities such as walking, running, and jumping.Rate this question:
