Study Notes
Muscle Tissue and Nervous System
- Thin Filament Components: Actin, Tropomyosin, and Troponin are components of the thin filament in muscle tissue. Myosin is NOT part of the thin filament.
- Chewing Muscles: Chewing muscles attach to the mandible (jawbone).
- Diencephalon Contents: The diencephalon includes the thalamus and hypothalamus.
- Cerebrospinal Fluid (CSF): CSF circulates within the subarachnoid space and is a protective fluid.
- Skeletal Muscle Stimulation: Skeletal muscle requires stimulation by a somatic motor neuron to contract.
- Occipital Lobe Function: The occipital lobe processes visual information in the primary visual cortex.
- Temporal Lobe Function: The temporal lobe contains the primary auditory cortex and processes auditory information.
- Myelin's Role: Myelin is the fatty insulating material that surrounds axons, increasing the speed of nerve impulse transmission.
- Medulla Oblongata Transition: The medulla oblongata transitions into the spinal cord as it descends.
- Arachnoid Mater Description: The arachnoid mater is a meninge resembling a spider web.
- Myelination Effect: Myelination increases the speed of action potential along the axon.
- Action Potential First Phase: The first phase of the action potential caused by inward sodium movement is depolarization.
- Intercostal Muscles: Intercostal muscles are located between the ribs and aid in breathing.
- Lower Extremity Muscle: The peroneus longus is a muscle located in the lower extremities.
- Hypothalamus Function: The hypothalamus controls the pituitary gland, regulates body temperature, and secretes releasing hormones.
- Actin's Structure: Actin is a contractile protein found in the thin filament.
- Occipital and Temporal Lobe Similarity: Both the occipital and temporal lobes are cerebral lobes.
- Calcium's Target Protein: Calcium binds to the contractile protein troponin.
- Subarachnoid Space Contents: Cerebrospinal fluid is located within the subarachnoid space.
