Study Notes
Nervous System Terminology
- "Hemi-" refers to "half," commonly used in anatomical terms such as hemispheres.
- "Caud-" means "tail," often used in the context of certain brain structures.
- "Dors-" indicates "back," utilized in terms related to spinal and brain orientation.
- "Cerebr-" denotes "brain," forming the root for various cerebral regions.
- "-itis" signifies "inflammation" or "disease," applicable to numerous medical conditions.
Brain Functionality
- The cerebrum is primarily responsible for learning, memory, and personality traits.
- The brain stem serves as a vital connection between the brain and the spinal cord, crucial for basic life functions.
Cerebellum Roles
- The cerebellum plays a significant role in planning and coordinating movement, ensuring fluid motion and posture.
Development of the Cerebellum
- The correct developmental pathway of the cerebellum is through the neural tube to the hindbrain and subsequently to the metencephalon.
Cerebral Cortex
- The majority of the cerebral cortex is composed of the neocortex, responsible for higher-order brain functions.
Hypothalamus Functions
- The hypothalamus regulates the autonomic nervous system, playing a central role in homeostasis and hormone secretion.
Components of the Limbic System
- The hippocampus and amygdala are integral parts of the limbic system, involved in emotions and memory processing.
Blood-Brain Barrier
- Components of the blood-brain barrier include tight junctions in brain capillaries, astrocytes, and endothelial cells, but meninges are not part of this barrier.
Cerebrospinal Fluid (CSF) Formation
- Cerebrospinal fluid (CSF) is created by choroid plexuses and reabsorbed through arachnoid granulation into dural sinuses.
Sensory and Motor Tracts
- Corticospinal tracts are responsible for motor control and do not carry sensory stimuli.
- In the spinal cord, motor information from the brain travels through the corticospinal tract.
Corticonuclear Tracts
- Corticonuclear tracts communicate with cranial nerve nuclei located in the brainstem, essential for controlling facial and head movements.
Circadian Rhythm
- Circadian rhythms dictate that within a 24-hour cycle, there are periods of being awake and asleep, reflecting the body's natural cycle.
Stages of Sleep
- The deepest stage of sleep occurs during Stage IV, essential for restorative processes.
Cognitive Functions
- The cerebral cortex is responsible for higher cognitive functions, such as reasoning and decision-making.
Prefrontal Cortex
- The prefrontal cortex is critical for personality, self-awareness, and recognizing appropriate social behavior.
Autonomic Nervous System
- The autonomic nervous system, which controls vital functions such as heart rate and digestion, is composed primarily of motor neurons rather than sensory neurons.
Blood-Brain Barrier Characteristics
- A key characteristic of the blood-brain barrier is the presence of tight junctions between the endothelial capillary cells, restricting permeability for certain substances.
