Locomotion & Movement: MCQ Test

Test your knowledge of human locomotion, muscle contraction, and skeletal system with these multiple-choice questions.

Test Your Knowledge

Showing questions 121 - 140 of 201

121. Pivot joint

At lanto Axial joint
Shoulder joint
Hip joint
None

A pivot joint allows for rotational movement around a central axis. The atlanto-axial joint, where the atlas rotates around the odontoid process of the axis, is a primary example, allowing for head rotation.

122. Study of joint known as

Osteology
Arthrology
Craniology
Kinesiology

The scientific study of joints, their structure, function, and disorders, is known as arthrology.

123. Study of skeleton is called

Endoskeleton
Osteology
Exoskeleton
Osteoblast

The branch of anatomy and biology dedicated to the study of bones, their structure, function, and diseases, is called osteology [information not from source].

124. Coracoid bone is found in

Pectoral girdle of rabbit
Pectoral girdle of man
Pectoral girdle of frog
Forelimb of rabbit

While in humans the coracoid is a process of the scapula (part of the pectoral girdle), in amphibians like the frog, the coracoid is a distinct bone forming part of their pectoral girdle [information not from source, but consistent with provided answer key].

125. The total number of bones in upper arm is

The entire skeleton of the human upper limb, comprising the arm, forearm, and hand, consists of a total of 30 bones.

126. The total number of bones in axial skeleton of adult human and rabbit are -

90,130
80,132
100,120
81,131

The axial skeleton of an adult human consists of 80 bones (skull, vertebral column, ribs, sternum). For the rabbit, the total number of bones in its axial skeleton is approximately 132.

127. Acetabulum is the part of

Hind arm
Pelvic girdle
Pectoral girdle
Fore arm

The acetabulum is a crucial component of the pelvic girdle, specifically the deep, cup-shaped socket formed by the ilium, ischium, and pubis that articulates with the head of the femur to form the hip joint.

128. Thoracic cage of man is formed of

Ribs
Sternum
Thoracic vertebrae
All

The thoracic cage (rib cage) in humans is a protective bony structure collectively formed by the thoracic vertebrae dorsally, the ribs laterally, and the sternum ventrally.

129. Function of skeleton is

Shape and symmetry
Protection
Physical supports to limbs
All

The skeletal system serves multiple vital functions including providing shape and symmetry to the body, offering protection for internal organs, and serving as physical support for the limbs and overall body structure [general knowledge, consistent with syllabus]. Therefore, all listed options are functions of the skeleton.

130. The pectoral & pelvic girdles and the bones of the limb form

Appendicular skeleton
Axial skeleton
Visceral skeleton
Outer skeleton

The appendicular skeleton is one of the two main divisions of the human skeletal system, consisting of the pectoral (shoulder) and pelvic girdles and all the bones of the upper and lower limbs.

131. The smallest bone in rabbit's and man's skeleton is

Stapes
Nasal
Patella
Dentine

The stapes (or stirrup) is the smallest of the three auditory ossicles located in the middle ear. It is recognized as the smallest bone in the human body and in most mammals like rabbits.

132. Funny bone of the body is

Humerus
Femur
Radius
Ulna

The sensation commonly referred to as hitting one's 'funny bone' is caused by striking the ulnar nerve as it passes through a groove on the medial epicondyle of the humerus (upper arm bone) [information not from source].

133. The second cervical vertebral process is called

Prezygapophysis
Odontoid process
Metaphysis
Post zygophysis

The odontoid process (dens) is the distinctive peg-like projection that extends superiorly from the body of the axis (second cervical vertebra). It serves as a pivot point for the atlas during head rotation.

134. Inter vertebral disc is a

Cartilage bone in the body
Pad in the centrum of a bone
Pad between two centrum
None of above

An intervertebral disc is a thick pad of fibrocartilage located between the bodies (centra) of adjacent movable vertebrae. These discs act as shock absorbers and allow for flexibility in the vertebral column.

135. A joint between humerus and radio Ulna

Ball & socket
Pivot
Gliding
Hinge

The joint formed by the articulation of the humerus with the radius and ulna (the elbow joint) is primarily a hinge joint, allowing for flexion and extension of the forearm.

136. The nutrient foramen is present in

skull of frog
Tibiofibula of frog
Radius - Ulna of rabbit
Pelvic girdle of frog & rabbit

A nutrient foramen is an opening in the shaft of a bone that allows for the passage of blood vessels supplying the bone marrow [information not from source]. The provided answer indicates its presence in the tibiofibula of a frog.

137. Which of following helps in rotation of the neck

Atlas
Axis
Cervical
Occipital condyle of skull

The axis (second cervical vertebra), with its odontoid process, acts as the central pivot around which the atlas and head rotate. This articulation is crucial for the rotational movements of the neck.

138. Largest foramen of human body is

Foramen ovale
Foramen of magendie
Foramen of magnum
Foramen of monro

The foramen magnum is the largest and most prominent opening in the human skull, located at the base of the occipital bone. It allows for the passage of the medulla oblongata to connect with the spinal cord.

139. Stapes is modification of

Hypomandibular
Palatine
Quadrate
Squamosal

The stapes, one of the three auditory ossicles, is evolutionarily considered a modified form of the hyomandibular bone from the ancestral jaw suspension.

140. A vertebra having convexity both in front and behind is-

Acoelous
Procoelous
Amphicoelous
Amphiplatyon

The term amphiplatyan refers to vertebrae that have flat articular surfaces on both their anterior and posterior sides [information not from source, but consistent with Q.44 Section A and its answer]. (Note: The literal description 'convexity both in front and behind' would typically describe a biconvex shape, which is not accurately represented by 'amphiplatyan'. The provided answer key (Amphiplatyan) indicates flat surfaces).
