Passive spinal movement under a load can increase the risk of spinal injury as the spine may be forced to move in ways that exceed its natural range of motion. This can potentially lead to strains, sprains, or disc herniation. It is important to use proper lifting techniques and avoid excessive bending or twisting of the spine when lifting heavy objects.
There are two types of spinal cord injuries. Complete spinal cord injuries refer to the types of injuries that result in complete loss of function below the level of the injury, while incomplete spinal cord injuries are those that result in some sensation and feeling below the point of injury. The level and degree of function in incomplete injuries is highly individual, and is dependent upon the way in which the spinal cord has been damaged. Complete spinal cord injuries result in complete paraplegia or complete tetraplegia. Complete paraplegia is described as permanent loss of motor and nerve function at T1 level or below, resulting in loss of sensation and movement in the legs, bowel, bladder, and sexual region. Arms and hands retain normal function. Some people with complete paraplegia have partial trunk movement, allowing them to stand or walk short distances with assistive equipment. In the majority of cases, complete paraplegics choose to get around via a self-propelled wheelchair. Complete tetraplegia is characterized by the loss of hand and arm movement as well. Some tetraplegics require ventilator systems in order to breathe. Depending upon the location of the injury, some tetraplegics may have some arm and hand movement present. Incomplete spinal cord injuries are more common than complete injuries, and are characterized by some degree of sensation and movement below the point of injury. The extent of an incomplete injury is generally determined after spinal shock has subsided, approximately six or eight weeks post injury. Incomplete spinal injuries can result in some feeling but little or no movement, or in some movement but little or no feeling. Incomplete spinal injuries fall under five different classifications: * Anterior cord syndrome: characterized by damage to the front of the spinal cord, resulting in impaired temperature, touch, and pain sensations below the point of injury. Some movement can later be recovered. * Central cord syndrome: characterized by damage in the center of the spinal cord that results in loss of function in the arms but some leg movement. Some recovery is possible. * Posterior cord syndrome: characterized by damage to the back of the spinal cord, resulting in good muscle power, pain, and temperature sensation, but poor coordination. * Brown-Sequard syndrome: characterized by damage to one side of the spinal cord, resulting in impaired loss of movement but preserved sensation on one side of the body, and preserved movement and loss of sensation on the other side of the body. * Cauda equina lesion: characterized by injury to the nerves located between the first and second lumbar region of the spine, resulting in partial or complete loss of sensation. In some cases, nerves regrow and function is recovered.
The somatic nervous system controls the skeletal system and voluntary movement by stimulating muscle contraction. Parts of the somatic nervous system are spinal nerves, cranial nerves, association nerves.
After surgery. Movement is severely limited for a period of time. This can be as long as six to eight months. Physical therapists assist. The patient can expect to remain under a physician's care for many months.
Yes, they have a spinal cord under their armor.

The movement of glacial ice is called glaciation or glacial flow. Glaciers move due to the force of gravity and the deformation of the ice under pressure. This movement can result in the formation of features like moraines, crevasses, and glacial valleys.

Yes, skeletal muscles are under voluntary control, meaning that we can consciously decide when to contract or relax them to perform movements. This control is facilitated by the motor neurons in the brain and spinal cord that send signals to the muscles to initiate movement.

Passive transport occurs when molecules move across a cell membrane without the use of energy. This process relies on the natural movement of molecules from areas of high concentration to areas of low concentration, down their concentration gradient. The main types of passive transport include diffusion, osmosis, and facilitated diffusion.
