Question

Define the following:

1. Streamlined

2. Pivotal joint

3. Synovial fluid​

Answer 1

streamlined

contoured to reduce resistance to motion through a fluid (such as air) b : stripped of nonessentials : compact. c : effectively integrated : organized.

pivotal joint

Pivot joints, also known as rotary joints, are a type of synovial joint that permit axial rotation. The moving bone rotates within a ring formed by the concave surface of a second bone and an adjoining ligament.

synovial fluid

Synovial fluid, also called synovia, is a viscous, non-Newtonian fluid found in the cavities of synovial joints. With its egg white–like consistency, the principle role of synovial fluid is to reduce friction between the articular cartilage of synovial joints during movement.

Answer 2

Answer:

1. Streamlined:-

contoured to reduce resistance to motion through a fluid (such as air).

2. Pivotal joint :-

3. Synovial fluid :-

Synovial fluid, also called synovia, is a viscous, non-Newtonian fluid found in the cavities of synovial joints. With its egg white–like consistency, the principle role of synovial fluid is to reduce friction between the articular cartilage of synovial joints during movement.
