Study Notes
Regions of the Body
- Human body divided into two broad regions: Axial and Appendicular.
- Axial Region: Includes head, neck, thorax, abdomen, pelvis, and perineum.
- Appendicular Region: Consists of upper and lower limbs.
Axial Region
- Also known as the torso or trunk.
- Comprises upper and lower limbs.
Upper Limb
- Components: Forearm, arm, elbow (cubital fossa), wrist, hand.
Lower Limb
- Components: Thigh, popliteal (back of the knee), leg, foot.
The Head
- Comprises the neurocranium (skull) and viscerocranium (face).
Neurocranium
- Includes scalp with superficial skin (hair, sweat glands) and cranial bones.
- Aponeurosis: Links frontalis and occipital muscles, contains blood vessels and nerves.
- Periosteum: Thin membrane covering the skull's outer surface.
Sphenoid Bone
- Forms part of the viscerocranium.
- Contains structures like the orbit, nasal cavity, maxilla, and mandible.
Viscerocranium
- Comprises facial muscles, tonsils, salivary glands, olfactory mucosa, and eyeball.
Neck
- Connects head to thorax, spans from the 1st to the 7th cervical vertebra.
- Contains structures such as the cricoid cartilage (Adam's apple), thyroid gland, trachea, and major blood vessels.
Thoracic Region
- Extends from the 1st thoracic vertebra to the diaphragm.
- Contains ribs, pleural cavities (lungs), and mediastinum (heart and other structures).
Abdomen Region
- Extends from the diaphragm to the pelvic floor.
- Houses critical visceral organs within the abdomenopelvic cavity.
Regions of the Abdomen
- RUQ: Right lobe of liver, hepatic flexure, right kidney.
- LUQ: Left lobe of liver, splenic flexure, left kidney.
- RLQ: Appendix, cecum, right ovary, right ureter.
- LLQ: Sigmoid colon, descending colon, left ovary, left ureter.
Planes of the Abdomen
- Midsagittal plane: Divides body into left and right halves.
- Transumbilical plane: Divides abdomen into upper and lower halves.
Upper Extremity
- Components: Arm, forearm, wrist, hand.
Arm
- Extends from shoulder to elbow.
- Contains the humerus and muscles (rotator cuff, flexor, extensor).
Forearm
- Extends from elbow to wrist, contains ulna (medial) and radius (lateral).
- Flexor Muscles: Include flexor carpi ulnaris and radialis.
- Extensor Muscles: Opposite of flexors.
Wrist
- Contains 8 carpal bones which articulate with the forearm and hand.
Muscles of the Hand
- Grouped into four categories: thenar, hypothenar, lumbricals, and interossei muscles.
- Thenar Muscles: Associated with the thumb (e.g., abductor pollicis).
- Hypothenar Muscles: Associated with the other fingers.
Summary
- The human body's anatomy is complex, with distinct regions and structures that perform various functions. Understanding the locations and connections of these body parts is crucial in anatomy and physiology studies.
