Concept
The thoracic spinal cord is a critical segment of the spinal cord located in the upper and middle back, responsible for transmitting neural signals between the brain and the body's trunk and some parts of the arms. It plays a pivotal role in controlling and coordinating movements and sensory information from the chest, abdomen, and back, making it essential for posture and balance.
Relevant Degrees
Concept
The spinal cord is a cylindrical structure of nervous tissue that extends from the brainstem to the lower back, acting as a conduit for signals between the brain and the rest of the body. It is organized into segments corresponding to vertebrae, with each segment giving rise to a pair of spinal nerves that control motor and sensory functions.
Concept
Concept
The somatic nervous system is a part of the peripheral nervous system responsible for voluntary muscle movements and the relay of sensory information to the central nervous system. It comprises motor neurons that control skeletal muscles and sensory neurons that convey information from the senses to the brain and spinal cord.
Concept
The autonomic nervous system (ANS) is a critical component of the peripheral nervous system responsible for regulating involuntary physiological functions, including heart rate, digestion, respiratory rate, and reflexes. It operates through two main divisions, the sympathetic and paraSympathetic Nervous Systems, which work in tandem to maintain homeostasis and respond to stressors.
Concept
Motor neurons are specialized nerve cells responsible for transmitting signals from the central nervous system to muscles, thereby enabling movement and coordination. They play a crucial role in voluntary and inVoluntary muscle activities, and their dysfunction can lead to severe motor disorders such as amyotrophic lateral sclerosis (ALS).
Concept
Sensory neurons are specialized nerve cells responsible for converting external stimuli from the organism's environment into internal electrical impulses. They play a crucial role in the sensory nervous system by transmitting information to the central nervous system for processing and response.
Concept
Reflex arcs are neural pathways that control reflex actions, allowing for rapid and involuntary responses to stimuli without direct involvement of the brain. They consist of a receptor, sensory neuron, integration center, motor neuron, and effector, ensuring efficient and automatic reactions to maintain homeostasis and protect the body from harm.
Concept
Concept
Neuroplasticity refers to the brain's remarkable ability to reorganize itself by forming new neural connections throughout life, allowing it to adapt to new experiences, learn new information, and recover from injuries. This dynamic process underscores the brain's capacity for change and adaptation, challenging the long-held belief that brain development is static after a certain age.
Concept
The central nervous system (CNS) is the primary control center for the body, consisting of the brain and spinal cord, and it processes and coordinates sensory information and responses. It plays a crucial role in regulating bodily functions, cognition, and behavior, making it essential for survival and adaptation to the environment.
Concept
The abdominal reflex is a superficial neurological reflex elicited by stroking the skin of the abdomen, leading to contraction of the abdominal muscles. It is used in clinical settings to assess the integrity of the thoracic spinal cord segments T7 to T12 and can help diagnose neurological conditions affecting these areas.
