2. Tissues

3. Epithelial tissue p60-62 Epithelium: Features of epithelium Mucus
Covers surfaces
lines cavities
forms glands
Features of epithelium
Mucus
Cilia
Glands
Exocrine glands
Endocrine glands
Repairs itself quickly after it is injured

4. Connective tissue p62-63
Supports and forms framework of all parts of body
Living cells in a matrix
Types of connective tissue
Circulating connective tissue
Generalized connective tissue
Structural connective tissue

5. Generalized connective tissue p63
Loose connective tissue
Adipose tissue
Dense connective tissue
Contains collagen
Organ capsules
Tendons
Ligaments
Elastic connective tissue

6. Structural connective tissue p64
Cartilage
Made by chondrocytes
Bone
Osteocytes
Osteoblasts
Osteoclasts

7. Muscle tissue p65-66 Skeletal muscle Cardiac muscle (myocardium)
Smooth muscle

8. Nerve tissue p67 Neuron Structure of neuron: dendrites axons myelin
Neuroglia are support cells for neurons

9. Membranes p67-68 Epithelial membranes Serous membranes
Mucous membranes
Cutaneous membrane

10. Serous membranes p69 visceral or parietal

11. Connective tissue membranes p69
Synovial membranes
Meninges
Fascia
Fibrous pericardium

Perichondrium

12. Tumors p70-71
Benign tumors
Malignant tumors

13. Symptoms of cancer p71 Unusual bleeding or discharge
Persistent indigestion
Chronic hoarseness or cough
Changes in color or size of moles
A sore that does not heal
Unusual lump
Late symptoms: weight loss and pain

14. Diagnosing cancer p71-72 Biopsy Radiography (x-ray) Ultrasound
Computed tomography (CT scan)
Magnetic resonance imaging (MRI)
Positron emission tomography (PET scan)

15. Cancer p72 Tumors are staged to establish extent of metastasis
Treatment:
Surgery
Radiation
Chemotherapy

16. Tissues and aging p73 Lose elasticity and collagen
Blood vessels have less capacity to expand
Tendons and ligaments stretch, causing a stooped posture
Bones lose calcium, becoming brittle and prone to fracture
Muscles atrophy
