The brain is the central organ of the human nervous system, and with the spinal cord makes up the central nervous system. The brain consists of the cerebrum, the brainstem and the cerebellum. It controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sense organs, and making ...
Anatomy of the human head. The human head consists of a fleshy outer portion, which surrounds the bony skull. The brain is enclosed within the skull. There are 22 bones in the human head. The head rests on the neck, and the seven cervical vertebrae support it. The human head typically weighs between 2.3 and 5 kilograms (5.1 and 11.0 lb) Over 98 ...
Cortical areas: Limbic lobe. Orbitofrontal cortex: a region in the frontal lobe involved in the process of decision-making. Piriform cortex: part of the olfactory system. Entorhinal cortex: related to memory and associative components. Hippocampus and associated structures: play a central role in the consolidation of new memories.
Orange: Temporal bone (2) Green: Occipital bone (1) Red: Ethmoid bone (1) In human anatomy, the neurocranium, also known as the braincase, brainpan, or brain-pan, [ 1 ][ 2 ] is the upper and back part of the skull, which forms a protective case around the brain. [ 3 ] In the human skull, the neurocranium includes the calvaria or skullcap.
The cerebral cortex is the outer covering of the surfaces of the cerebral hemispheres and is folded into peaks called gyri, and grooves called sulci. In the human brain, it is between 2 and 3-4 mm. thick, [ 8] and makes up 40% of the brain's mass. [ 2] 90% of the cerebral cortex is the six-layered neocortex whilst the other 10% made up of three ...
Table of cranial nerves. Located in the cribriform plate of the ethmoid bone . Animal research indicates that the terminal nerve is involved in the detection of pheromones. [ 2] Located in the olfactory foramina in the cribriform plate of the ethmoid bone . Transmits the sense of smell from the nasal cavity. [ 3]
The human body is the entire structure of a human being. It is composed of many different types of cells that together create tissues and subsequently organs and then organ systems. The external human body consists of a head, hair, neck, torso (which includes the thorax and abdomen ), genitals, arms, hands, legs, and feet.
The human musculoskeletal system (also known as the human locomotor system, and previously the activity system) is an organ system that gives humans the ability to move using their muscular and skeletal systems. The musculoskeletal system provides form, support, stability, and movement to the body. It is made up of the bones of the skeleton ...
