Study Notes
Human Body
- Composed of 11 organ systems that work together to maintain homeostasis
- Organ systems:
- Nervous system
- Circulatory system
- Respiratory system
- Digestive system
- Endocrine system
- Immune system
- Integumentary system
- Muscular system
- Skeletal system
- Urinary system
- Reproductive system
Reflexes
- Automatic responses to stimuli
- Do not involve the brain, but rather the spinal cord
- Examples:
- Withdrawal reflex (e.g., pulling hand away from heat)
- Stretch reflex (e.g., knee-jerk reaction)
- Tendon reflex (e.g., tapping on the patellar tendon)
Nervous System
- Composed of:
- Central nervous system (CNS): brain and spinal cord
- Peripheral nervous system (PNS): nerves that connect CNS to the rest of the body
- Functions:
- Controls and coordinates body functions
- Interprets and responds to stimuli
- Facilitates communication between different parts of the body
Emotional Response
- Also known as the "fight or flight" response
- Triggered by the release of hormones (e.g., adrenaline) in response to stress or danger
- Physiological responses:
- Increased heart rate and blood pressure
- Rapid breathing and increased oxygen intake
- Increased glucose release for energy
- Enhanced mental focus and concentration
Sensory Receptors
- Specialized cells or organs that detect and respond to stimuli
- Types:
- Mechanoreceptors (e.g., touch, pressure, vibration)
- Photoreceptors (e.g., light, vision)
- Thermoreceptors (e.g., temperature)
- Chemoreceptors (e.g., taste, smell)
- Nociceptors (e.g., pain)
Good Behavior (Not directly related to Human Anatomy, but included in the topic list)
- Not a specific concept in human anatomy, but rather a general term
- Can refer to various aspects of behavior, such as:
- Social behavior (e.g., cooperation, empathy)
- Emotional regulation (e.g., self-control, emotional intelligence)
- Moral behavior (e.g., honesty, fairness)
- Healthy habits (e.g., regular exercise, balanced diet)
