This flattened part of the skull and the depressed region above the zygomatic arch constitute the temporal fossa which in life is occupied by the temporalis muscle. 1 6. ANS -B: The middle meningeal artery and accessory meningeal artery are branches of the max illary artery that enter the cranial cavity through foramen spinosum and foramen ovale. 1 7. ANS -B: The buccal branch of the facial nerve is the motor fo r the buccinator muscle.
Correct The structure that separates the left and right cerebral hemispheres is the: Your Answer: Longitudinal fissure. 2. Correct The lobe of the brain involved with the coordination of autonomic functions is the: Your Answer: Insula. 3. Correct The structure of the brain that regulates the endocrine system is the: Your Answer: Hypothalamus.
- The occipital lobe. e) What lobe would process words that we speak? - The frontal lobe. 4. The brain and spinal cord comprise the __central__ nervous system.
• the spinal cord is an extension of the brain. It runs from the base of the brain to just below the level of the
a. Temporal Hemiretina - to provide an optic tract to opposite hemifields, it has a relationship with the nasal Hemiretina which creates the input to be processed further. b. Optic chiasm – Signals are passed from each eye to meet each other at the optic chiasm, signals are crossed to meet together in both parts of the visual cortex. c. Optic track – It is the pathway for sight the organization of it. Containing axons from the ganglion cells that are in the retina of each eye, but only one passes on the information for the visual field d. Geniculate nuclei – Or Lateral geniculate nuclei (LGN)has six layers which gathers input the contraor ipsilateral eye.
Trace the process of interpreting auditory information from the stimulus to the interpretation. The primary auditory cortex is the primary destination for most info in the auditory system. The cortex processes the hearing. 8. Name and describe the major structures of the middle ear.
Often the midbrains, pons and medulla are referred together as brainstem. The telencephalon comprises of three elements which are the cortex, limbic system and the basal ganglia whilst the Diencephalon consists of the thalamus and hypothalamus. THE FOREBRAIN THE CEREBRAL CORTEX The cerebral cortex is a thin mantle of gray matter covering the surface of each cerebral hemisphere. The most notable features of the telencephalon are the two large and roughly symmetrical hemispheres’ which are in fact separate functional systems interconnected by major fibre pathways called the cerebral commissures. The principal commissures is the corpus callosum which according to Nearve (2008) literally means “hard body” and this wrist –thick bundle of fibres connects the corresponding regions of
When I first saw the brain the first thing I noticed was the deep longitudinal fissure that divided the cerebrum in two halves: the left hemisphere and the right hemispheres. Also the surface of the brain was covered with large folds of tissue called gyri. The grooves between the gyri are sulci. The small rounded structure at the back of the brain, I noticed, was the cerebellum. Later, when I turned the brain over, the most prominent structure visible was the optical chiasma, where two optic nerves cross over each other.
The resonating system is located in the pharynx, oral cavity, and nasal cavities. The vocal tract is comprised of resonators which give a personal quality to the voice, and the modifiers or articulators which form sound into voiced sounds. There are three different cartilages used in our larynx which are the thyroid, cricoid, and arytenoid. The thyroid cartilage forms the front portion of the larynx; the most forward part comprises the "Adam's apple". The vocal folds attach just below the Adam's apple, and the thyroid cartilage also houses the vocal folds.
The occipital lobes (the lower back head region) are employed with special recognition and vision. The cerebellum (behind the brain stem) deals with balance, movement coordination, and posture. AD targets specific nerve cells (neurons) in the cerebellum. These lost neurons are regenerated by the hippocampus of the brain. It also regulates emotions and is a part of the cerebral cortex that deals with smell.
