If the patient and the caregiver are not in the right position when changing from the bed to the chair, a lot can go wrong. If the patient does not have the right support they could fall and injure themselves along with the caregiver and the caregiver needs to have the right angle to be able to support the patient because if they try to move too fast, the patient may get dizzy an the caregiver could easily hurt themselves too.
Axons are long nerve processes which carry nerve impulses from the Soma to other neurons, they vary in length but can become almost as long as half of the human body.
The soma (body) of the neuron contains the nucleus which acts as the cell's control centre, these contain many small neurofibrils which project from the nucleus into the dendrites.
Dendrites are short, thick processes which branch out of the soma in a tree like manor. They conduct nerve impulses to the soma.
The three categories of neurons:
Afferent (Sensory) Neurons have the dendrites connected to receptors such as the eyes, ears etc. These receptors change the information they receive into electrical impulses that are transmitted to other neurons. In sensory neurons the axons are connected to other neurons.
Efferent (Motor) Neurons have the dendrites connected to other neurons, the axons are connected to effectors. Effectors are either glands or a muscle cell that is the receiving end of the nerve impulse. The nerve, when excited will cause the effector to react (move, contract, or secrete etc).
Internuncial Neurons have both the dendrites and the axons are connected to other neurons. They are sometimes referred to as connector neurons.
Internuncial neurons are found throughout the body, but especially in the spinal cord and brain.
Properties and characteristics of Neurons:
Normally the electrical impulses (messages) travel through a neuron in only one direction.
The axon may be surrounded by a 'coat' of lipids (fats) and proteins known as the myelin sheath which acts as an insulator.
Neurons are specialist cells that have lost the ability to reproduce themselves. Once the soma of a neuron has died the entire neuron dies, and can never be replaced.
Repair of damaged neurons only occurs in myelinated neurons.
white matter are coloured by myelin, consisting of many neurons supported by neuroglia.
grey matter is soma and dendrites or bundles of unmyelinated axons and neuralgia.
Answer: See explanation
Explanation:
• Stability: this is defined as the ability of a certain body to go back to its original position or equilibrium when such body is displaced.
• Maximum Effort: This is the use of maximum force towards accomplishing a particular objective e.g lifting of weight.
• Maximum Velocity: Thus is the maximum speed that a certain body uses to move in a particular direction. We should note that when there's maximum speed, there's acceleration is zero.
• Impluse: It is the effect of a force that acts over time.
• Reaction:
• Torque: It is the rate of change that occurs in the angular momentum of a certain object.
• Angular Momentum: It measures the rotational momentum that occurs in a system.
Answer:
Weight must not be confused with the mass of an object which is a fundamental property of the object expressed in kilogram (kg). Therefore, the mass of an object on the Moon remains the same as its mass on Earth. But its weight gets less because the gravity on the moon is less than on the Earth.

Explanation:
Curative expenditure treats the disease as well as eases the pain, and is thus concerned as consumption spending. Preventive health care accumulates health stock as well as increases the number of days available to participate in market and non-market activities, which in turn stimulates goods production.
These services are defined as "The process of enabling people to increase control over their health and its determinants, and thereby improve their health".
relating to or used in the cure of diseases : tending to cure. 2 law : serving to correct or negate We have instructed that if a complaint is vulnerable to … dismissal, a district court must permit a curative amendment, unless an amendment would be inequitable or futile.
