Chapter 1 A&P I

1. THORACIC CAVITY-chest cavity

   • pleura cavity-surrounds the lungs(pleural)
   • pericardial cavity-surrounds the heart(pericardium)
   • mediastinum-central portion of thoracic cavity b/w lungs extends from sternum to vertebral cavity and from first rib to diaphragm

2. ABDOMINOPELVIC CAVITY

   • abdominal cavity-contains stomach,spleen,liver gallbladder,small intestine and most of large intestine
   • pelvic cavity-unrinary bladder, portions of large intestines and internal organs of reproduction(peritoneum)
   • 1.right hypochondriac/2.epigastric/3.left hypochondriac/4.right lumbar/5.umbilical/6.left lumbar/7.right inguinal/8.hypogastric/9.leftminguinal
     • 2.spleen,colon,left kid.,pancreas
       • 1.liver,gallbladder,right kid.,small int.
     • 3.stomach,liver,pancreas,duodenum,spleen,adrenal glands
     • 4.gallbladder,liver,right colon
     • 5. descending colon,left kid.
       • 6.umbilicus,jejunum,lluem,duodenum
         • 7.appendix,cecum
           • 8.descending colon,sigmoid colon
             • 9.urinary bladder,sigmoid colon,female repro. organs

3. CRANIAL CAVITY- BRAIN

4. VERTEBRAL CAVITY- contains spinal cord(extension of brain)

5. 6 LIFE PROCESSES-metabolism/responsiveness/movement/growth/differentiation/reproduction

6. HOMEOSTASIS

   • COMPONENTS:
     • RECEPTORS-send nerve impulses to control center i.e. thermostat
     • CONTROL CENTER-brain and spinal cord;receives
     • EFFECTORS-bring about change;i.e. AC
   • NEG. FEEDBACK
     • blood pressure goes up
       • picked up by receptors-corroted arteries
         • sends change to blood pressure
           • goes to brain resisters info goes to heart and blood vessels
             • decrease in heart rate; dilation in blood vessels cause pressure to decrease
   • POS. FEEDBACK
     • child birth
       • oxyrocin-cause dilation and contractions in cervix and uterus

7. cephalic-head
