Why does rigor mortis affect the muscles and not the limbs?
Rigor mortis affects the muscles throughout the body, including the limbs, due to biochemical changes that occur after death. When the body ceases to produce ATP, the energy molecule required for muscle relaxation, myosin heads remain attached to actin filaments, causing the muscles to stiffen. This process is not limited to limbs but affects all skeletal muscles, leading to a generalized rigidity. Thus, rigor mortis manifests in the muscles themselves, which include those in the limbs.
What two body systems that make up our limbs move?
The two body systems that enable movement in our limbs are the muscular system and the skeletal system. The skeletal system provides the framework and structure for the limbs, while the muscular system facilitates movement through muscle contractions. Muscles attach to bones via tendons, allowing for coordinated movement when the muscles contract and relax. Together, these systems work in harmony to allow for a wide range of motions in the arms and legs.
What two body systems work together closely to produce movement in human limbs?
The musculoskeletal system and the nervous system work closely together to produce movement in human limbs. The musculoskeletal system includes muscles, bones, and joints, which work together to create movement and provide stability. The nervous system controls muscle contractions through signals sent from the brain, allowing for coordinated and precise movements.
How does the skeletal and muscular system work in a spider?
In spiders, the skeletal system is their exoskeleton, composed of chitin, which provides support and protection. Their muscles are attached to the inside of the exoskeleton and work in antagonistic pairs to move the spider's limbs by contracting and relaxing. This coordinated effort allows spiders to move, hunt, and perform various functions.
What types of muscle tissue are found in humans?
In the bones of the body
What organ system moves the limbs?
The muscular system is responsible for moving the limbs. Muscles work in coordination with the skeletal system to produce movement. Nerves from the nervous system send signals to the muscles to contract and allow for precise control of limb movement.

How do the skeletal muscles move the limbs?
they attract each other causing friction
How does the skeletal system interact whit the muscular system?
Our muscles are fastened to the skeleton so that we can move our limbs.
Which two body system work together closely to produce movement in human limbs?
The muscular system and the skeletal system work closely together to produce movement in human limbs. Muscles contract and pull on bones, which act as levers to create movement at the joints. Coordination between these two systems allows for smooth and precise movement in response to signals from the nervous system.
What two body systems make up our limbs?
The two body systems that make up our limbs are the skeletal system and the muscular system. The skeletal system provides the framework and support through bones, while the muscular system enables movement through muscles attached to these bones. Together, they facilitate mobility and physical activity in the limbs.
Is a skeletal muscle the same as a striated muscle?
Yes, skeletal muscles are voluntary, meaning they can be intentionally controlled. This distinguishes them from the cardiac muscle (heart) and smooth muscles, which are involuntary.
Which organ system moves the limbs?
The muscular system moves the limbs by contracting and relaxing muscles. This system works in conjunction with the skeletal system, which provides structure and support for movement. Coordination of these systems allows for precise and coordinated movements of the limbs.
What muscles in the limbs are the effectors of a withdrawal reflex?
Flexor Muscles

Do tortoise have endoskeleton?
Yes, tortoise have endoskeleton as they generally use to move on the ground with their limbs as, limbs have muscles and without the combination of muscles and skeletal system we cannot loco mote. Tortoise have exoskeleton also because it help tortoise to protect from several enemy like crocodile, snake, fox etc.
Skeletal muscle fibers are typically voluntary?
Yes! These muscles run along the long bones of your body such as your femur and humerus! You can control this limbs freely therefore you control the muscle fibers attached to them!
