Study Notes
Human Anatomy and Physiology
Systems of the Body
- Integumentary system: skin
- Endocrine system: hormones
- Lymphatic system: immune system
- Urinary system: waste removal
- Homeostasis: maintenance system to keep stable conditions within the body
Homeostasis
- Negative feedback mechanism: reverses or negates any potentially detrimental changes to the body by reverting to a normal value
- Positive feedback mechanism: reinforces or promotes changes from previous state to an optimal state
- Homeostatic imbalance: a disturbance in homeostasis resulting in diseases or death
Anatomical Language
Axial Areas
- Cephalic: head
- Cranial: skull
- Facial: face
- Vertebral: spinal column
- Umbilical: navel (belly button)
- Thoracic: chest
- Lumbar: lower back
- Sacral: sacrum (located at the base of the pelvis)
Appendicular Areas
Upper Limb
- Acromial: acromion of the shoulder (bump of the shoulder)
- Antebrachial: forearm
- Axillary: armpit
- Brachial: arm
- Carpal: wrist
- Cubital: elbow
- Dorsum of the hand: back of the hand
- Palmar: palm of the hand
- Scapular: scapula
Lower Limb
- Calcaneal: heel
- Coxal: hip
- Crucal: leg
- Dorsum of foot: top of the foot
- Femoral: thigh
- Gluteal: buttocks
- Patellar: front of the knee
- Plantar: sole of the foot
- Popliteal: back of the knee
- Tarsal: ankle
Anatomical Directions
- Anterior: front
- Ventral: towards the belly
- Posterior: back
- Dorsal: towards the back
- Superior: on top, above
- Cephalic/cranial: towards the head
- Inferior: below, underneath
- Caudal: towards the tail
- Lateral: away from the midline, towards the side
- Medial: towards the midline
- Proximal: nearer to the trunk of the body
- Distal: furthest from the trunk of the body
- Deep: away from the body surface
- Superficial: closer to the external surface
Anatomical Planes
- Axial: cuts the body horizontally into superior and inferior portions
- Coronal: cuts the body vertically into posterior and anterior portions
- Sagittal: cuts the body vertically in the midline of the body into left and right portions
Major Body Cavities
Dorsal Cavity
- Consists of two smaller cavities: cranial cavity and vertebral cavity
- Cranial cavity: superior portion, bounded by the skull, consists of brain and meninges
- Vertebral cavity: inferior portion, known as spinal cavity, consists of vertebral column, intervertebral discs, ligaments, spinal cord, and spinal nerve roots
Thoracic Cavity
- Bounded laterally by the ribs and inferiorly by the diaphragm
- Consists of mediastinum, pericardial, and pleural cavities
Abdominal Cavity
- A large cavity found inferior to the diaphragm
- Contains the gastrointestinal tract, spleen, kidneys, and adrenal glands
- Bound laterally by the body wall and inferiorly by the pelvic cavity
Pelvic Cavity
- Inferior to the brim of the pelvis
- Contains the urinary bladder, internal genitalia, sigmoid colon, and rectum
- Bound superiorly by the abdominal cavity, posteriorly by the sacrum, and laterally by the pelvis
Regions of the Abdomen
- Quadrants of the abdomen (right upper, right lower, left upper, left lower)
