Study Notes
Location and Structure
- The brain stem is the lower part of the brain that connects to the spinal cord
- It is divided into three main parts: midbrain, pons, and medulla oblongata
- The brain stem is responsible for controlling many of the body's automatic functions
Functions
- Regulates breathing, heart rate, and blood pressure
- Controls body temperature, hunger, and thirst
- Manages sleep and wakefulness
- Processes sensory information from the face and head
- Plays a role in regulating posture, balance, and movement
Cranial Nerves
- The brain stem is the origin of 10 of the 12 cranial nerves
- These nerves are responsible for controlling various functions such as:
- Smell and taste
- Eye movement and vision
- Hearing and balance
- Facial expressions and sensation
- Swallowing and salivation
Damage and Disorders
- Damage to the brain stem can result in serious consequences, including:
- Respiratory failure
- Coma
- Death
- Disorders affecting the brain stem include:
- Stroke
- Traumatic brain injury
- Brain tumors
- Infections such as meningitis and encephalitis
Brain Stem Structure
- Located at the base of the brain, connecting to the spinal cord
- Divided into three main parts: midbrain, pons, and medulla oblongata
Brain Stem Functions
- Regulates vital functions:
- Breathing
- Heart rate
- Blood pressure
- Controls:
- Body temperature
- Hunger
- Thirst
- Manages:
- Sleep and wakefulness
- Posture and balance
- Movement
- Processes sensory information from the face and head
Cranial Nerves
- 10 out of 12 cranial nerves originate from the brain stem
- These nerves control various functions, including:
- Smell and taste
- Eye movement and vision
- Hearing and balance
- Facial expressions and sensation
- Swallowing and salivation
Damage and Disorders
- Brain stem damage can lead to severe consequences, including:
- Respiratory failure
- Coma
- Death
- Disorders affecting the brain stem include:
- Stroke
- Traumatic brain injury
- Brain tumors
- Infections (e.g., meningitis and encephalitis)
