AN INTRODUCTION TO ANATOMY SKIN FASCIA MUSCLES VESSELS

AN INTRODUCTION TO ANATOMY

SKIN, FASCIA, MUSCLES, VESSELS Objectives: 1. Distinguish the two layers of the skin & its appendages 2. Note how skin changes over different body parts & relate it to tension lines. 3. Distinguish the two types of fascia 4. Identify the types of muscles 5. Identify the parts of a skeletal muscle & how to study it/Compare smooth to skeletal muscles 6. Distinguish arteries from veins & capillaries 7. Understand lymph formation & circulation

THE SKIN

TENSION LINES

FASCIA Deep Superficial (C. T. ) Epimysium Periosteum (bone) Septa Epineurium (muscles) (nerve) Sheath (blood vessels & nerves) Fatty T. all over the body

MUSCLE TYPES

SKELETAL MUSCLE PARTS

VESSELS Blood Arteries Veins Lymphatic Capillaries Afferent & Efferet

THE BLOOD AND LYMPHATIC VESSELS

ANASTOMOSIS & VENOUS PLEXUSES

LYMPH

THE BLOOD AND LYMPHATIC VESSELS

BONES & JOINTS Objectives: 1. Identify the anatomical & histological types of bone 2. Identify the types of cartilage 3. Divide the skeleton into its major parts 4. Define a joint & its major types 5. Identify the types of synovial joints, factors that affect their stability & the movements they perform

THE NERVOUS SYSTEM Objectives: 1. Review the structure of a typical nerve cell 2. Understand the structure & appearance of a nerve 3. Understand the anatomical divisions of the nervous system 4. Identify the major parts of a spinal nerve 5. Locate the origin & distribution of the sympathetic & parasympathetic nervous systems
