Which brain structure plays a key role in personality development and emotional behavior?
Which brain structure plays a key role in personality development and emotional behavior?
The frontal lobe is vital for personality development and the expression of emotional behavior.
What are the biceps femoris, semitendinosus, and semimembranosus muscles called?
What are the biceps femoris, semitendinosus, and semimembranosus muscles called?
The biceps femoris, semitendinosus, and semimembranosus muscles are collectively known as hamstrings. These muscles are located at the back of the thigh and are responsible for knee flexion and hip extension.
What does cerebrospinal fluid (CSF) do?
What does cerebrospinal fluid (CSF) do?
Cerebrospinal fluid (CSF) is a clear fluid that circulates around the central nervous system (CNS) within the subarachnoid space. The choroid plexus produces CSF, and it normally does not contain blood.

Study Notes
Nervous System Structures and Functions
- Frontal Lobe: Key role in personality development and emotional expression.
- Hamstrings: Includes biceps femoris, semitendinosus, and semimembranosus muscles.
- Cerebrospinal Fluid (CSF): Circulates around the CNS in the subarachnoid space, formed by the choroid plexus; typically does not contain blood.
- Myelination: Increases the speed of nerve impulses along the axon.
- Abdominal Muscles: Include rectus, transversus, internal oblique, and external oblique muscles.
- Corpus Callosum: Connects the right and left cerebral hemispheres.
- Neuromuscular Junction: Acetylcholine binds to nicotinic receptors on the muscle membrane.
- Cerebrum: Composed of frontal, temporal, occipital, and parietal lobes.
- Convolutions (Gyri): Fold-like elevations on the cerebrum's surface.
- Tendons: Attach muscles to bone.
- Sarcoplasmic Reticulum: Stores calcium in relaxed skeletal muscle.
- Latissimus Dorsi: Muscle located on the posterior body.
- Sternocleidomastoid: Muscle that rotates the head down and to the left or right, and also moves the head down and to the left or right.
- Brainstem: Composed of midbrain, pons, and medulla oblongata.
- Creatine Phosphate: Elevated blood levels indicate muscle damage.
Other Anatomical Structures and Functions
- Subarachnoid Space: Contains cerebrospinal fluid (CSF).
- Corpus Callosum: Connects the right and left cerebral hemispheres.
- Zygomaticus: Known as the "smiling muscle".
- Foramen Magnum: Passage through which the medulla oblongata descends into the vertebral cavity.
- Neuron: Conduct nerve impulses.
- Acetylcholine: Released by somatic motor neurons at the neuromuscular junction.
- Mastication Muscles: Insert into the mandible.
- Medulla Oblongata: An infratentorial structure, sensitive to opioids, located within the brainstem.
- Meninges: Protective layers that surround the brain and spinal cord.
- Diaphragm: Chief breathing muscle, separating the thoracic and abdominal cavities.
- Myelin: Makes white matter white in color.
- Axon Terminals: Store neurotransmitters.
- Levator Palpebrae Superioris: Raises the eyelids.
