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.
