Study Notes
Nervous System
- Two main components: Central Nervous System (CNS) and Peripheral Nervous System (PNS)
- CNS consists of brain and spinal cord
- PNS mainly consists of nerves
Spinal Vertebrae
- Cervical spine - 7 vertebrae (C1-C7), in the neck
- Thoracic spine - 12 vertebrae (T1-T12), in the upper back/rib cage
- Lumbar spine - 5 vertebrae (L1-L5), in the lower back
- Sacrum spine - 5 fused vertebrae (S1-S5), in the pelvis/base of spine
- Coccyx spine - 3-5 fused vertebrae, tailbone
Respiratory Muscles
- Intercostal muscles
- External intercostals are primary inspiratory muscles
- Internal intercostals are accessory expiratory muscles
- Abdominal muscles are accessory expiratory muscles
Bones
- Long bones: support body weight, facilitate movement, located in lower limbs
- Short bones: provide support and stability, little movement, located in wrist and ankle joints
- Flat bones: skull, thoracic cage (sternum and ribs), protect internal organs (brain, heart)
- Irregular bones: complex shapes, vary, help protect internal organs (e.g., vertebral column protects spinal cord)
Gastrointestinal Tract (GIT)
- Mouth: beginning of the digestive tract.
- Throat (pharynx): where food travels.
- Esophagus: delivers food to the stomach.
- Stomach: sac-like organ that mixes food.
- Small intestines (duodenum, jejunum, ileum): 20 feet long, involved in nutrient absorption via peristalsis.
- Large intestines (colon): 7 feet long, divided into four parts (ascending, transverse, descending, sigmoid), involved in water reabsorption.
