Study Notes
Organ System Overview
- Muscular system: consists of skeletal muscles that contract or shorten to produce movement of bones
- Nervous system: fast-acting control system that responds to internal and external changes by sending messages via nerve impulses to the central nervous system
- Endocrine system: consists of endocrine glands that secrete regulatory hormones to control processes such as growth, reproduction, and metabolism
Nervous System
- Consists of brain, spinal cord, nerves, and sensory receptors
- Activates effectors (muscles and glands) to respond to internal and external changes
Endocrine System
- Glands include: pituitary gland, thyroid and parathyroid glands, adrenal glands, thymus, pancreas, ovaries (females), and testes (males)
- Secretes hormones that regulate growth, reproduction, and metabolism
Muscular System
- Skeletal muscles contract or shorten to produce movement of bones
- Maintains posture, produces heat, and allows manipulation of the environment and locomotion
Skeletal System
- Consists of bones, cartilages, ligaments, and joints
- Supports the body, provides muscle attachment for movement, and is the site of blood cell formation (hematopoiesis)
Integumentary System
- Forms the external body covering (skin)
- Protects deeper tissue from injury, helps regulate body temperature, and is the location of cutaneous nerve receptors
Body Planes and Sections
- Sagittal section: divides the body into left and right halves
- Median or mid-sagittal section: divides the body into equal left and right halves
Regional Terms
- Regional terms used to designate specific body areas:
- Cephalic (head)
- Frontal (forehead)
- Orbital (eye socket)
- Nasal (nose)
- Buccal (cheek)
- Mental (chin)
- Cervical (neck)
- Thoracic (chest)
- Axillary (armpit)
- Abdominal (abdomen)
- Umbilical (navel)
- Pelvic (pelvis)
- Inguinal (groin)
Directional Terms
- Superior (toward the head or upper part of the body)
- Inferior (away from the head or toward the lower part of the body)
- Ventral (toward the front of the body)
- Dorsal (toward the back of the body)
Body Cavities
- Oral and digestive cavities
- Nasal cavity
- Orbital cavities
- Middle ear cavities
- Abdominopelvic cavity
Abdominopelvic Regions
- Nine regions:
- Right upper quadrant (RUQ)
- Right lower quadrant (RLQ)
- Left upper quadrant (LUQ)
- Left lower quadrant (LLQ)
- Right hypochondriac region
- Epigastric region
- Left hypochondriac region
- Umbilical region
- Pubic region
