The Nervous System MDCAT Quiz helps out the students in gaining extensive knowledge about the human nervous system as a basic requirement for medical and dental college admission tests. The nervous system supports all the body functions in relation to movement and consciousness. Thus, this quiz will cover all the important aspects- the structure of the nervous system, its sub-divisions, such as central and peripheral, and what the different parts do. All MDCAT candidates should familiarize themselves with these topics, as they will be the bases of many physiological and anatomical subjects in medicine.
Nervous System Structure
The nervous system consists of two large divisions: central nervous system (CNS) and peripheral nervous system (PNS). The CNS contains the brain and spinal cord, which are the control centers of the body; the CNS processes information and gives out responses. The PNS refers to all the nerves extending from the CNS to the rest of the body, thereby allowing communication between the brain, spinal cord, and different organs. These two systems must be understood by MDCAT students as they often come up in both theory and practical exam questions.
Functions of Nervous System
The nervous system has a number of vital functions for survival. It detects stimuli, such as temperature or pain, through sensory receptors. It plays a significant role in integration by processing incoming sensory information to form appropriate responses. Lastly, the nervous system coordinates motor functions by sending signals to muscles and glands to ensure the body responds effectively to environmental changes. MDCAT students must understand how these functions are interrelated and how the nervous system maintains overall body homeostasis. Mastery of these concepts is essential for success in the exam.
Quiz for MDCAT Preparation
For students preparing for the MDCAT, this MDCAT quiz offers a thorough review of the nervous system’s structure and functions. There are multiple-choice questions in the quiz, which test knowledge of the divisions of the nervous system, neural pathways, the function of different components in the body, among other things. Taking the quiz periodically helps in fortifying memories regarding the nervous system and equips any MDCAT student to face the day of the exam confidently and with an excellent grasp of the key concepts.
