degeneration and regeneration of muscle fibers + reaction to those changes (infiltration by fat and connective tissue); no abnormal storage of metabolic products.
4. All symptoms are effects of striated muscle weakness (heart and visceral muscles may also be involved).
5. Weakness becomes progressively worse (i.e. not static – vs. congenital myopathies, metabolic myopathies).
Enamel
√ Hard and white substance covering the teeth
√ The hardest and most highly mineralized
√ Protects the fragile underlying parts of the teeth
√ Covers the crown and supported by dentin
Component of enamel
√ 96% of enamel : mineral, water, organic material
√ contain two unique classes of proteins amelogenins and enamelins
√ The basic unit of enamel is called

1) 세포벽의 구조
셀룰로오스와 기타 다당류로 구성된 미세섬유로 되어있다. 미세섬유는 각도를 다르게하여 이루어져 있으며 탄성을 가진다. 세포분열시 완전히 분리가 되면 펙틴과 함께 굳어지며 중엽을 형성한다.

Ⅰ. Ischaemic heart disease
Ischaemic heart disease
Ischaemic heart disease (IHD), or myocardial ischaemia, is a disease characterized by ischaemia (reduced blood supply) of the heart muscle, usually due to coronary artery disease (atherosclerosis of the coronary arteries). Its risk increases with age, smoking, hypercholesterolaemia (high cholesterol levels), diabetes, and hypertension (hig
Occlusive aortic disease caused by atherosclerosis
: usually confined to the distal abdominal aorta below the renal arteries
The severity of the symptoms depends on the adequacy of collaterals
With sufficient collateral blood flow
: a complete occlusion of the abdominal aorta may occur without the development of ischemic symptoms.
