Answer:
Slightly movable joints permit some movement but provide less stability than immovable joints. These joints can be structurally classified as cartilaginous joints, as bones are connected by cartilage at the joints. Cartilage is a tough, elastic connective tissue that helps to reduce friction between bones.
Answer:
d. adrenal cortex
Explanation:
Aldosterone is secreted by the adrenal cortex and helps regulate blood pressure.
Answer: B. Subcutaneous emphysema
Explanation:
Subcutaneous means tissue layer beneath the skin. Emphysema means trapping of air.
Subcutaneous emphasema is a condition in which the air enters inside the skin. It usually occurs in the regions of chest cavity, face, and neck. It gives a crackling feel when touched.
Answer: Poor motor control impairs;
--> the smoothness and
--> accuracy of joint movement.
Explanation:
The peripheral nervous system controls the motor system in vertebrates. The motor system also consists of two parts which includes:
--> The somatic nervous system and
--> The autonomic nervous system.
The motor neurones that carry instructions to voluntary muscles, that is, those muscles that we can control consciously, makes up the SOMATIC NERVOUS SYSTEM. These motor neurons are part of some of the spinal and cranial nerves. Their cell bodies are in the central nervous system; their nerve fibres extend all the way to the skeletal muscles
Impulses that speed along these fibres stimulate( excite) the muscles to being about the appropriate movements.
The somatic nervous system controls all skeletal movements. These movements include:
--> all voluntary actions like clapping ( which we can choose to do or not to do), and
--> control of the body equilibrium
Poor muscle control can occur due to injury, illness, or inherited disorder. An individual with poor muscle control is at a higher risk of joint pain and injury because of the damage to the motor neurones that innervates the skeletal muscles attached to joints. This is turn will lead to a decrease in the smoothness and accuracy of joint movement.
Nystagmus or repeated sweeping movement of the eye during neurologic evaluation indicates a vestibular problem within the brainstem.
<h3>
What is Nystagmus? </h3>
- A condition of vision where the eyes make repetitive, uncontrolled movements is termed as Nystagmus.
- Reduced vision and depth perception are the results and can affect balance and coordination.
- Both eyes are unable to steadily view objects as the involuntary eye movements occur from up and down, side to side or in a circular pattern.
- A patient with nystagmus might nod and hold their heads in unusual positions to compensate for the condition.
- Fatigue and stress make this condition even worse. The cause of this is unknown.
