Answer: Option A. -> 1. Ethmoid, 2. Sphenoid, 3. Frontal, 4. Parietal, 5.Temporal, 6.Occipital
:
A
The cranium, made up of cranial bones, is the portion that houses the brain. There is a total of 8 cranial bones, including 2 temporal bones, 2 parietal bones, 1 frontal bone, 1 occipital bone, 1 sphenoid bone and 1 ethmoid bone. These project from either side of the central body of the bone called the Pterygoid processes. Ethmoid bone has lots of perforations through which the olfactory nerve, the nerve that senses smell, leaves the nose on its way to the brain. It is this perforation that gives it its name.The sphenoid forms the base of the cranium as well as forming part of the orbit that houses the eye, amongst other function.

Answer: Option D. -> Clavicle
:
D
Wishboneis a forked bone found in birds and some dinosaurs and is formed by the fusion of the twoclavicles

Answer: Option C. -> Rheumatoid arthritis
:
C
Rheumatoid arthritisis a consequence of changes in the body's immune system which (for reasons not fully understood) attacks the soft tissue of the joints causinginflammation,swellingandpain.The joint is contained within a joint capsule, which is lined by asynovialmembrane (synovium). Asprainis a stretch or tear of a ligament while astrainis an injury to a muscle or tendon.Osteoarthritis(OA) is a type of joint disease that results from the breakdown of joint cartilage and underlying bone.

Answer: Option A. -> Presence of odontoid process
:
A
TheAtlasandAxis Vertebrae(diagram below), the first and second cervical vertebrae, are the most distinctive in terms of size and morphology. TheAtlasbone (C1) lies between the cranium (connecting with the condyles of the occipital bone)and the Axis vertebrae (C2). The atlas lacks a ‘vertebral body, a spinous process and has no articular disks either superior or inferior to it.TheAxisbone also lacks a typical vertebral body. It’s most distinctive feature is the odontoid peg, as seen in the diagram below.

Answer: Option B. -> Endomysium     
:
B
Sarcolemma is the cell membrane that encloses each muscle (which is also known as a muscle fibre).Endomysium is connective tissue that wraps each individual muscle fibre.Perimysium is connective tissue that wraps bundles of muscle fibres - the "bundles" being known as fasicles. Epimysiumis connective tissue that wraps the whole muscle.Fascia (or "deep fascia") is a layer of thickened connective tissue that covers the entire muscle and is located over the layer of epimysium.

Answer: Option B. -> Thoracic vertebrae, ribs and sternum
:
B
Rib cage is the bony structure forming the boundaries for the thorax, which is also called as thoracic cage. It is made up of thoracic vertebra posteriorly, sternum anteriorly and ribs connecting the two structures passing laterally.

Answer: Option B. -> Pectoral girdle
:
B
Glenoid cavity is a shallow depression in the scapula into which head of the humerus articulates to form an important component of the pectoral girdle.
Pelvic girdle has a shallow depression into which the femur fits.
Theskullis a bony structure that forms the head of the skeleton in most vertebrates.
Thesternumor breastbone is a long flat bone shaped like a necktie located in the center of the chest.

Answer: Option A. -> Phosphocreatine
:
A
Phosphagen is a high-energy phosphoric ester that serves as a reservoir of phosphate-bond energy, as phosphocreatine in vertebrates.

Answer: Option A. -> Ligaments
:
A
Syndesmology is the study of ligamnets.Ligaments are made of tough connective tissues and connect bone to bone.
Myology is the medical specialty concerned with thestudyof the structure, function, and diseases and disorders ofmuscles.

Answer: Option A. -> Femur
:
A
Femur, or thighbone, is the largest bone in your body.
Thestapesis the third bone of the three ossicles in the middle ear.
Thehumerusis a long bone in the arm or forelimb that runs from the shoulder to the elbow.
Thepatellaalso known as the kneecap or kneepan, is a thick, circular-triangular bone.
