Peripheral nervous system
The peripheral nervous system consists of sensory and motor neurons that connect the central nervous system to organs and other parts of the body outside the brain and spinal cord. It carries information between the body and central nervous system through 12 pairs of cranial nerves that control the head, neck, and face and 31 pairs of spinal nerves that connect to the spinal cord. The peripheral nervous system is divided into the somatic and autonomic systems, with the somatic controlling skeletal muscles voluntarily and the autonomic regulating involuntary functions through the sympathetic and parasympathetic divisions.

It is made up of gray and white matter containing neurons, axons and dendrites. The cerebrum is the largest part and is divided into lobes each with different functions.
Hypothalaums & limbic system
The limbic system includes structures like the amygdala, hippocampus, thalamus, hypothalamus, and cingulate gyrus that work together to regulate emotion, memory, and arousal. The thalamus relays motor and sensory signals to the cortex and is involved in sensory processing, arousal, alertness, reflexes, and emotions. The hypothalamus regulates body temperature, hunger, circadian rhythms, hormone release, and the autonomic nervous system to control functions like digestion and emotion expression.
Thalamus and Hypothalamus.pdf
The diencephalon includes the thalamus and hypothalamus. The thalamus relays sensory information, except smell, to the cortex and is involved in arousal, motor integration, pain modulation, and memory/behavior. The hypothalamus regulates homeostasis through the endocrine, autonomic, and motivational systems. It contains peptidergic neurons that secrete hormones through the pituitary to control endocrine functions. The thalamus and hypothalamus are critical for sensory/motor processing, arousal, homeostasis, and motivated behavior.
Powerpoint for hank revised
The human brain contains over 100 billion neurons that form over 100 trillion connections. Neurons communicate via electrical and chemical signals, transmitting messages through synapses. Different parts of the brain control different functions - the cerebellum coordinates movement, brainstem regulates vital functions, cerebrum is divided into left and right hemispheres connected by the corpus callosum. Within the cerebrum, the frontal lobe controls thinking and movement, parietal lobe processes sensory information, temporal lobe processes images and memory, and occipital lobe interprets visual input. The limbic system regulates emotion and the hippocampus processes short-term memory. The brainstem connects to the spinal cord which extends messages between the brain and body.
Nervous system
Nervous system consists of highly complex structure co-ordinates and controls the body along with the endocrine system.

The brain
The document discusses various parts of the brain including the brain stem, cerebellum, thalamus, limbic system, hypothalamus, pituitary gland, cerebral cortex, frontal lobe, and their functions. Key points include that the brain stem controls basic life functions like breathing and heart rate. The cerebellum controls balance and movement coordination. The limbic system is involved in emotions and memory. The hypothalamus regulates body temperature, hunger, thirst and circadian rhythms. The pituitary gland influences other endocrine glands. The cerebral cortex is responsible for thought, reasoning and voluntary movement. The frontal lobe is involved in motor function, problem solving and social behavior.
Peripheral nervous system,Central nervous system
The peripheral nervous system has two main subsystems - the somatic nervous system and the autonomic nervous system. The autonomic nervous system can be further divided into the sympathetic and parasympathetic nervous systems. The sympathetic nervous system prepares the body for fight or flight responses while the parasympathetic nervous system helps with rest and digestion. There are also 31 pairs of spinal nerves that carry signals between the brain/spinal cord and the rest of the body. The cranial nerves similarly connect the brain to different parts of the head and neck.
The Brain
The cerebrum is the largest part of the human brain and consists of two hemispheres divided into four lobes. It is important for functions like memory, learning, emotions. The cerebellum is located behind the brainstem and helps with muscle tone, balance, and coordinated movement. The medulla oblongata is the lowest part of the brainstem and controls involuntary functions such as breathing and heart rate. The hypothalamus is located below the thalamus and cerebrum and regulates processes including body temperature, thirst, hunger and sexual function.
Powerpoint for hank
The human brain contains over 100 billion neurons that form over 100 trillion connections. Neurons communicate via electrical and chemical signals to control functions like movement, thinking, senses, and language. The cerebrum is divided into four lobes - frontal, parietal, occipital, and temporal - each controlling different functions like planning, senses, vision, and memory. Deeper brain structures like the brainstem regulate vital functions, while the cerebellum coordinates movement. Overall, the brain's complex network of neurons allows for intricate cognitive and physical processes.

Introduction to Anatomy and Physiology
Anatomy is the study of the structure of the body. It covers the microscopic and macroscopic structure of the body and how body parts develop. Anatomy also examines the relationship between structure and function. The study of anatomy includes looking at body systems, regions, external features, and using imaging technologies. Physiology is the study of function in living organisms. The goals of physiology are to understand how the body responds to stimuli and maintains stable internal conditions despite external changes. Anatomy identifies and describes body structures, while physiology examines their functions.

Medical terminology used to describe body positions and regions is also reviewed.
Reproductive new
The male and female reproductive systems work together to produce offspring. The male system produces and transfers sperm and the male sex hormone testosterone. The female system produces eggs and the female sex hormones estrogen and progesterone. It receives sperm and nourishes the development of offspring. Both systems also produce gametes and hormones through complex processes regulated by the brain and hormones.
Cardio physio
The heart functions to pump blood throughout the body via two circulatory systems - pulmonary and systemic. It generates blood pressure and ensures one-way blood flow. Cardiac output, the amount of blood pumped, is determined by heart rate and stroke volume. Intrinsic factors like the Frank-Starling mechanism and extrinsic neural and hormonal controls regulate cardiac output in response to the body's changing needs.
Respiratory system
The document provides information on the respiratory system including its main functions and the anatomy and physiology of key structures. It discusses the nose and nasal cavity including the external nares, nasal septum, conchae and paranasal sinuses.

Chapter 7 muscular
The document summarizes the structure and function of skeletal muscle. It describes the sarcomere as the basic structural and functional unit of skeletal muscle, containing actin and myosin filaments. It explains how skeletal muscle contracts through neural stimulation of the neuromuscular junction, which causes the release of calcium and interaction of actin and myosin, leading to muscle fiber shortening. It also lists some of the key functions of skeletal muscle like body movement, posture maintenance, and respiration.
Cranium of the skull copy
The skull is composed of multiple bones that form the neurocranium and viscerocranium. The neurocranium includes the frontal, parietal, occipital, sphenoid, ethmoid and temporal bones. The viscerocranium includes the zygomatic, maxilla, nasal, lacrimal, vomer, palatine, inferior nasal concha and mandible bones. Foramina in the skull allow for the transmission of blood vessels and cranial nerves. Common fractures include those of the nasal bones, basilar skull, maxillofacial bones and orbit.
Special senses
1. The special senses include vision, hearing, balance, smell, taste and touch.
2. The ear is responsible for both hearing and balance. It contains the cochlea for hearing and the vestibular system for balance.
3. In the cochlea, sound waves are converted into electrical signals via hair cells that detect vibrations. These signals are sent to the brain.
The vestibular system contains canals and otolith organs that detect movement and position. It helps maintain equilibrium and senses acceleration and rotation.
Endocrine system - drjopogs
The endocrine system consists of glands that secrete hormones directly into the bloodstream to regulate various bodily functions. The major glands include the pituitary, thyroid, parathyroid, adrenal, pancreas, ovaries, and testes. Hormones act as chemical messengers on target tissues by binding to receptors and altering cellular activity. Common hormones include growth hormone, thyroid hormones, insulin, glucagon, estrogen, progesterone, and testosterone. The pituitary gland controls other endocrine glands by secreting hormones like TSH, ACTH, and gonadotropins.
Chapter 6 skeletal
The skeletal system chapter discusses the components and functions of the skeletal system. There are 206 bones in the human body that serve various functions including support, protection, movement, storage, and blood cell production. Bones are made of tissues like compact bone, spongy bone, cartilage, tendons, and ligaments. Long bones have a diaphysis, epiphyses, and growth plates. Bones grow through endochondral ossification and are remodeled through the actions of osteoblasts and osteoclasts. Calcium homeostasis is maintained through the actions of parathyroid hormone and calcitonin. The bone marrow produces blood cells.
Chapter 5 integumentary
The integumentary system consists of the skin, hair, nails, and glands. The skin has three layers - the epidermis, dermis, and hypodermis - and performs several important functions like protection, sensation, temperature regulation, and vitamin D production. It is the body's largest organ. The epidermis is made of stratified squamous epithelium and undergoes keratinization. The dermis contains collagen, fibers, and glands. Hair, nails, and glands are also components of the integumentary system. The system helps regulate body temperature and protects against microbes and UV light.

Cell Therapy Expansion and Challenges in Autoimmune Disease
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.
