Coat color in mammals is controlled by a hormone receptor called the melanocortin receptor. When this receptor is bound by the hormone MSH, pigment cells produce dark eumelanin. When the receptor is bound by an MSH antagonist that prevents MSH binding, pigment cells make yellow/red pheomelanin. In the Irish Setter, the overall red coat color could be due to a mutation in the a. receptor that prevents the antagonist from binding. b. receptor that prevents MSH from binding. c. MSH protein such that it binds the receptor more efficiently. d. antagonist such that it no longer binds to the receptor.
Musculoskeletal System
The musculoskeletal system, also called the locomotor system, is an organ system that gives humans and animals the ability to move using their muscular and skeletal systems. It provides stability, form, support, and movement to the body. The skeleton is composed of bones (skeleton), muscles, cartilage, tendons, ligaments, joints, and other connective tissue that supports and binds tissues and organs together. The musculoskeletal system is subdivided into two broad systems, such as the muscular system and the skeletal system.
Skeletal structure
The skeletal system is the core framework of the human body. The skeletal structure comprises bones and connective tissue, including cartilage, ligaments, and tendons. The skeletal structure of our body acts as a support structure. It maintains the body's shape and is responsible for its movement, blood cell formation, protection of organs, and mineral storage. The skeletal system is referred to as the musculoskeletal system.
