Answer:
The correct option is B) Papillary
Explanation:
The thick layer of skin present between the subcutaneous tissues and the epidermis (outermost layer of skin), is known as the dermis. The dermis consists of elastic and fibrous tissues, which cushions the body from any external stress.
The dermis consists of two sub layers- the papillary region and the reticular dermis.
The papillary dermis is the uppermost layer present in the pepillary region of the dermis.
Therefore, papillary is a stratum or sub-layer of the dermis.
A chronic, progressive neuromuscular disease that is characterized by extreme muscular weakness (generally appearing first in the face) and progressive fatigue as the day progresses is Myasthenia gravis.
A neuromuscular condition called myasthenia gravis is largely characterized by muscle wasting and weakening. Despite the fact that the condition typically only becomes obvious in adulthood, symptoms can start to manifest at any age.
Ocular myasthenia is a disorder that only affects certain muscle groups, mainly those in the eyes. Generalized Myasthenia Gravis, on the other hand, affects a variety of muscle groups.
The majority of people with myasthenia gravis experience increased muscle tiredness after exertion, ptosis (weakness and drooping of the eyelids), diplopia (double vision), and weak eye muscles. Additionally, facial muscle weakness, dysarthria, which impairs speech, dysphagia, which causes difficulty chewing and swallowing, and weakness in the upper arms and legs are all frequent symptoms (proximal limb weakness).

Answer:
Mitosis is a method of cell division in which a cell divides and produces identical copies of itself. The primary mechanism by which organisms generate new cells is through cell division. During this process, a single "parent" cell will divide and produce identical "daughter" cells.
