Skull and Brain structures Flashcards
skull makes up ____ bones
22
Cranium is comprised of ___ bones making up the sides and back of skull
8
What bones make up the cranium
Partiel, Temporal, Occupital, Sephnoid
Face (front portion od the skull) is comprised of ___ bones
14
What bones make up the face
Frontal, nasal, lacrimental, orbital, vomer, maxilla, mandible, zygomatic TMJ tempormandibluar joint
The skull is held together by
Sutures
Frontal lobe do
The lobe at the front of the brain associated with movement, speech, and impulsive behavior.
parietal lobe
portion of the cerebral cortex lying at the top of the head and toward the rear; receives sensory input for touch and body position
occipital lobe
A region of the cerebral cortex that processes visual information
limbic lobe
emotion and memory; located in center of brain under celebral cortex
Thalamus
the brain’s sensory switchboard, located on top of the brainstem; it directs messages to the sensory receiving areas in the cortex and transmits replies to the cerebellum and medulla
pineal gland
produces melatonin, which helps maintain circadian rhythm and regulate reproductive hormones
Cerebellum
A large structure of the hindbrain that controls fine motor skills.
spinal cord
Nerves that run up and down the length of the back and transmit most messages between the body and brain
medulla oblongata
Lowest part of the brainstem that controls vital life-sustaining functions such as heartbeat, breathing, blood pressure, and digestion.
Pons
A brain structure that relays information from the cerebellum to the rest of the brain
mammillary body
one of a pair of limbic system structures that are connected to the hypothalamus; act primarily as a hippocampal relay, passing information on to the anterior thalamic nuclei and from there to the cingulate cortex
putuitary gland
The endocrine system’s most influential gland. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands.
Hypothalamus
controls pituitary gland ; a small part of the brain that regulates many bodily functions, such as temperature, hunger, thirst, mood, sleep and hormones
Optic Schiasma
formed when the optic nerves come together in order two allow eyesight
corpus callosum
the large band of neural fibers connecting the two brain hemispheres and carrying messages between them
cerebral cortex
mostly consists of the six-layered neocortex, with just 10% consisting of allocortex. The cerebral cortex is responsible for integrating sensory impulses, directing motor activity, and controlling higher intellectual functions. It plays a key role in attention, perception, awareness, thought, memory, language, and consciousness
The cerebral cortex is folded in a way that allows a large surface area of neural tissue to fit within the skull. There are four main lobes: the frontal lobe, parietal lobe, temporal lobe, and occipital lobe1.
