Where is the axis located on the body?
The Axis is the second vertebra in your spinal column right at the top.
What is the Definition of longitudinal axis?
longitudinal axis: An axis along the lengthwise direction of the figure or body, usually passing through its center of gravity.
Why do planets have axis?
The axis just defines their rotation. It is relative to spin, so if a body does not spin, it has no axis. Kind of an imaginary line, like the equator. It is used for reference. Also an object that is not round and symmetrical and has a length and a width can also be referenced by these dimensions. The Longitudinal axis is usually an axis through the longest dimension of the body.
What the axis of the body?
The axis of the body refers to an imaginary line around which the body rotates or is organized. In anatomical terms, it typically includes the vertebral column (spine) as the central structure, providing support and alignment for the body. This axis plays a crucial role in maintaining balance, posture, and facilitating movement. It can also be understood in terms of different planes of motion, such as the sagittal, frontal, and transverse axes.
What is the comparison between the body axis of a four legged animal to the axis of a human?
The body axis of a four-legged animal, or quadruped, typically runs horizontally from the head to the tail, allowing for stable locomotion and weight distribution across the four limbs. In contrast, the body axis of a human is vertical, supporting bipedalism and enabling an upright posture. This difference in orientation affects locomotion, balance, and the overall structure of the musculoskeletal system in each type of organism. Additionally, the horizontal axis of quadrupeds facilitates agility and speed in various terrains, while the vertical axis of humans supports complex upper body movements and dexterity.
Which fascicles run with the long axis of the muscle?
Parallel
Moment of inertia of parallel axis?
This is known as parallel axes theorem. Statement: If IG be the moment of inertia of a body of mass M about an axis passing through its centre of gravity, then MI (I) of the same body about a parallel axis at a distance 'a' from the previous axis will be given as I = IG + M a2
What is the Muscle that revolves a part of the body on its axis?
rotator.
What fascicle arrangement does the rectus femoris have?
The rectus femoris muscle has a parallel fascicle arrangement, meaning its muscle fibers run parallel to the long axis of the muscle. This arrangement allows for strong contraction forces and efficient movement.
If moment of inertia of a body change of axis of rotation?
If the moment of inertia of a body changes due to a change of axis of rotation, the new moment of inertia can be calculated using the parallel axis theorem. This theorem states that the moment of inertia about a new axis parallel to the original axis can be found by adding the mass of the body multiplied by the square of the distance between the two axes.
The extensor digitorum longus has which type of fascicle arrangement?
The extensor digitorum longus muscle has a parallel fascicle arrangement where muscle fibers run parallel to the long axis of the muscle. This arrangement allows the muscle to generate a strong pulling force to extend the toes.
What does it mean when you get a x-ray and your back is parallel to the film?
The long axis of the image receptor (film) runs parallel with the long axis of your body. In other words, the line that measures the length of the image receptor will run parallel to the line that measures the length of the body.
State and prove the parallel axis theorem?
the moment of inertia of a body about a given axis is equal to the sum of its moment of inertia about a parallel axis passing through its centre of mass and the product of its mass and square of perpendicular distance between two axis Iz=Ix+Iy
What is parallel axis theorem?
The parallel axis theorem is a principle in physics and engineering that allows the calculation of the moment of inertia of a rigid body about any axis parallel to an axis through its center of mass. It states that the moment of inertia ( I ) about the new axis is equal to the moment of inertia ( I_{cm} ) about the center of mass axis plus the product of the mass ( m ) of the body and the square of the distance ( d ) between the two axes: ( I = I_{cm} + md^2 ). This theorem is particularly useful in rotational dynamics for analyzing systems with complex shapes.
What is the nature of the distance time graphs for a body at rest?
As the body is at rest, its distance from some point is not changing, so the graph will be a straight line parallel to the time axis (including the possibility of being on the time axis).
How do you compare the body axis of a four-legged animal to the body axis of a human?
The body axis of a four-legged animal is typically horizontal, with the spine running parallel to the ground and limbs extending out to the sides. In contrast, the body axis of a human is vertical, with the spine running perpendicular to the ground and limbs extending downward. This difference in body axis affects posture, movement, and overall body structure between the two types of animals.
What types of joint movement occurs when a muscle moves a body part around its axis?
rotation
