Question

Humans are able to move their shoulder 360 degrees. What morphological features aid in this degree of motion (i.e. which bones)? Examine the bat wing below. Is there the same degree of motion? Explain why or why not.

Answer 1

This question is incomplete because of the absence of bat diagram discussed in the question

Step-by-step explanation:

Humans body contains several joints that allows from movement of bones at some junctions called the "joints". Joints are points where two bones meet. Examples of the human joints include the ball and socket joints, hinge joint, pivot joint, gliding joint, saddle joint. The type of joint in the human shoulder that allows for 360 degrees rotation is the ball and socket joint. It involves a bone that has a round head like that of a "ball" which can fit into an open cup-like shape called the "socket", hence the reason for the name. This joint allows for movement in all directions.

The bat wing does not move at the same degrees (360°) as it does not move in all directions - the wing has an up and down movement which is more of a 180° movement and not a 360° movement.
