Glenoid cavity articulates
- clavicle with scapula
- humerus with scapula
- clavicle with acromion
scapula with acromion
The Correct Option is B
Solution and Explanation
The glenoid cavity is a shallow cavity found on the scapula bone. Scapula, also known as shoulder blade, is a triangular bone which along with clavicle constitute the pectoral girdle.
The upper bone of the arm is called as humerus. Its upper end is rounded which is called the head of the humerus. This rounded head articulates into the glenoid cavity forming a glenohumeral joint or shoulder joint. This joint is a type of ball and socket joint that allows free movement of our hands. Biceps brachii, a tendon, keeps humerus within the glenoid cavity.
The joint formed between the clavicle and acromion of the scapula is called acromioclavicular joint. It forms the roof of the shoulder.

Locomotion and Movement
Locomotion
The movement of a creature from one place to another is known as locomotion. During the process, there is the action of appendages such as wings, limbs, and flagella. In some animals, like fish, whales, and sharks, locomotion upshots from a wave-like series of muscle contractions. Locomotion helps an organism in finding their food, avoid harsh weather conditions, escape from their predators, etc.
Some examples of locomotion are walking, running, swimming, etc. Movement, on the other hand, refers to any type of motion that need not be localized.

Movement
Movement is generally described as a state of changing the position from rest to motion or vice-versa. Movement can be both voluntary movement and involuntary movement. Movement helps an organism perform essential functions, such as pumping blood to the different parts of the body, etc.
