Study Notes
Organization of the Human Body and Homeostatic Mechanisms
- The hypothalamus regulates body temperature through heat generating and conserving activities such as shivering and blood vessel constriction when body temperature drops, and sweat gland stimulation and blood vessel dilation when body temperature rises.
- Homeostatic mechanisms maintain stable conditions in the body through negative feedback, but some operate through positive feedback, which intensifies the change initially instead of reversing it.
- Examples of positive feedback mechanisms in the body include blood clotting and uterine contractions during childbirth.
- The human body is divided into two major divisions: the axial portion (head, neck, trunk, and viscera) and the appendicular portion (upper and lower limbs).
- The human body contains various body cavities, including the cranial cavity (holds the brain), vertebral cavity (holds the spinal cord), thoracic cavity (houses the lungs and thoracic viscera), and abdominopelvic cavity (contains abdominal and pelvic viscera).
- The abdominopelvic cavity is further divided into the abdominal cavity (holds organs such as the stomach, liver, and intestines) and the pelvic cavity (contains the urinary bladder and reproductive organs).
- The body also has smaller cavities within the head, including the oral cavity, nasal cavity, orbital cavity, and middle ear cavity.
- The human body consists of several organ systems, including the integumentary system (skin, hair, nails), skeletal system (bones, ligaments, cartilage), muscular system (muscles), nervous system (brain, spinal cord, nerves), endocrine system (glands that secrete hormones), cardiovascular system (heart, blood vessels), lymphatic system (lymphatic vessels, lymph nodes), digestive system (organs involved in food digestion and absorption), respiratory system (organs involved in breathing), urinary system (kidneys, bladder), and reproductive system (male and female reproductive organs).
- Each organ system has specific functions, such as protecting tissues (integumentary system), providing support and movement (skeletal system), producing and maintaining sperm and eggs (reproductive system), and transporting substances throughout the body (cardiovascular system).
- Anatomical terminology is used to describe the relative positions of body parts, body sections, and body regions.
- Some examples of anatomical terms include superior (above), inferior (below), anterior (front), posterior (back), medial (towards the midline), lateral (away from the midline), proximal (closer to the point of attachment), distal (further from the point of attachment), superficial (near the surface), and deep (away from the surface).
- Body regions are divided into nine abdominal regions (epigastric, hypochondriac, umbilical, lumbar, hypogastric, and iliac) and four abdominal quadrants (right upper, right lower, left upper, and left lower). Specific body regions
